Play the music you do now, in any key, while using only one finger on the fretboard!

(Don’t want to go through all the details? JUMP TO THE SUMMARY.)

I designed One Finger Ukulele because my old hands were wearing out and because I knew someone who’d lost his left thumb and a finger in an accident but still wanted to play. It hurt for me to quickly switch between chord shapes and he could no longer do some shapes at all.

With One Finger Ukulele, by tuning a baritone differently or re-stringing and retuning a tenor uke, you can play all the chords you need to all the songs you want to play, by only barring one finger. And by adding a few single note licks here and there, you can play rich, full, performance level accompaniments to sing along with. For newbies, we offer quality, low cost ukuleles that have been customized with chord markers along the neck, or you can tweak a spare ukulele that you already own in the same way.You can check out our ukuleles HERE.

I’m posting this online because I feel that it will be beneficial to people who can’t handle regular playing styles. I think it might also tickle the creative urges of others. Feel free to email anytime with questions or comments:

About One Finger Ukulele–a message before you begin.

Watch the videos, download the songbook!

One Finger Ukulele is an easy to learn method of playing that uses a different tuning of the instrument. This alternate tuning will allow you to play almost every chord in any uke songbook while using only one finger on the fretboard. The basic concepts are these:

– Most common chords are made up of the 1st and 5th notes of a scale, plus a 3rd or flat 3rd, and sometimes additional notes.

– With One Finger Ukulele, you play the same 1st and 5th notes while replacing the ‘other notes’ by playing the 1 & 5 in two octaves.

– With this strategy, you can play all the chords you need to play with one finger shape. HOWEVER you can also get complicated and add licks and melodies if you like, as there are many opportunities to play individual notes over the top of the droning, open chord that the uke is re-tuned to.

Note: The finger SHAPE is a BAR, but newbies, don’t be afraid: it’s not as hard as a regular GCEA bar. Since no additional fingers are required other than your index, while you’re building strength you can use your middle finger on top of your index.

One Finger Ukulele is not meant to replace normal GCEA tuning, but you may find that you prefer it for many types of songs. In the guitar world, artists such as Keith Richards, Ry Cooder, Joni Mitchell, Laurence Juber, Leo Kottke, David Lindley, Robert Fripp, David Wilcox, and more all favor alternate tunings. Music should be fun and the One Finger Ukulele method is just that!

Newbies: You’ll be able to quickly learn to accompany yourself or jam with others in any key with One Finger Ukulele!

Uke Adventurers: One Finger Ukulele makes complex melody lines and licks more accessible to more players. By experimenting with single note positions on one string you will quickly find that those notes duplicate on the second string above or below where you are playing, either an octave above or below. This makes for fun “lick experimentation!”

We’ve customized a line of ukuleles with special strings and Chordfinders along the side of the neck to help you find your way instantly! Check out our ukuleles here or tweak one you already own in the same way.

More about the barring process:
The “one finger” in One Finger Ukulele refers to a single finger barring the width of the neck on a given fret. In regular tuning, barre chords can be difficult because you must also put down other fingers, but with One Finger Ukulele other fingers are not required. This means that you can help your index finger by pushing your middle finger down on top of it until you get stronger. With your thumb kept approximately in the center of the back of the neck you’ll have maximum pinching/barring power without other fingers weakening the overall structure. You’ll find One Finger barring much easier and, over time, you will actually build up strength for the more difficult barring of regular GCEA tuning.

Instrument Requirements
One Finger Ukulele began as a baritone-only system, however the popularity of GCEA ukuleles required that I bring tenor ukes into the fold. (Anything smaller than tenor doesn’t work well with One Finger ukulele.)

There are many advantages in using a baritone:
– No re-stringing required.
– The longer neck gives easier access to chords up the neck.
– The lower string tension lessens strain on your hands.
– The larger body best compliments the tones of the power chords.

To match One Finger tuning on a tenor, you must change strings. Therefore you should keep a separate tenor uke set up for this system, assuming you still want to play GCEA regularly. With a baritone you only need one instrument.

What tuning does One Finger Ukulele use?
Because the key of C is the most practical and is the easiest to understand, we tune to the C power chord of CGCG. This allows you to easily play in all popular ukulele keys.


How to convert your ukulele to a One Finger Ukulele
Baritone: Tuning a baritone to CGCG is easy. From standard DGBE baritone tuning, tune the 4th string from D down to C (1 full step down). Leave the 3rd string at G. Tune the 2nd string from B up to C (1/2 step). Tune the 1st string from E up to G (1 1/2 steps).

Tenor: Tuning a tenor to CGCG requires changing strings. (You can tune a tenor with standard GCEA strings to another power chord but the key would be impractical for playing music with others.) You will need two new wound strings: one in the range of .039-.041 and one in the range of .029-.031.


If you source them yourself, make sure they are nylon/classical guitar strings-NOT steel! 

Here is the process of re-stringing your tenor:
Leave the existing 1st/A string in place.

Move the existing 3rd/C string to the 2nd position, discarding the old 2nd string.
Place the wound +/- .030 string in the 3rd position.
Place the wound +/-  .040 string in the 4th position.*
*The nut slot may be too small for the new 4th string. You can enlarge the slot with a needle nose file or even a fingernail file.

Tune the 4th string to C, the 3rd string to G, the 2nd string to C, and the 1st string down one full step to G.

*** Or just get a baritone! ***

NOTE: For both of the above ukuleles, the proper pitches on a keyboard are:
4th string-C below middle C
3rd string-G below middle C
2nd string-middle C
1st string-G above middle C

The hardest thing about One Finger Ukulele
You will need to learn the fret positions of the notes along the 4th string. That’s why we install chord markers on the side of the neck of out One Finger Ukuleles! Of course you can always mark the notes on the side of your neck.

Why One Finger Ukulele works
Here’s just a smackerel of “music theory.” You do not need to remember it, but it doesn’t hurt to know why the method works. One Finger Ukulele borrows from the rock ‘n roll world’s concept of “power chords.” What is a power chord? To answer that we must first look at regular chords.

A major chord, such as C Major, is made up of the 1-3-5 notes in the root-note’s scale. So C Major is composed of the notes CEG: (1C 2D 3E 4F 5G). The other three most common chord types found in ukulele music are minor chords (such as Am), 7th chords (such as G7), and minor-7th chords (such as Dm7). Those chord types are created by flattening the 3 note, adding a note above the 5 note, or both. But the 1 & 5 notes are never altered. (Many other chord types, such as Maj7, 6 chords, suspended chords, and more also retain unaltered 1 & 5 notes.)

A power chord consists only of the 1 and 5 notes, that is, the root note and the fifth note of a scale. (This is also called a 5 chord.) Therefore, if you re-tune your ukulele so that all strings are either the 1 or 5 notes of a scale, barring* a finger across any fret will give you a “5 chord” or “power chord” version of the root note of that fret. This power chord will substitute for or sound good with any major, minor, 7th, minor 7th, Major 7th, 6th, etc. chord and more.

How to find and play the chords
1) Look at the letter of the chords being played–ignore everything past the letter*
2) Find that chord letter along the 4th string
3) Bar that fret and strum!
* except dim chords. See page 7 for those rascals

Here are the notes along the 4th string:

A more rich and full sound
In One Finger Ukulele, you are doubling the playing of the 1 & 5 notes. In other words, you are playing in two octaves. If you are playing with others and they are playing any common chords, your power chords will add to the overall sound! You will be playing the 1&5 notes of the chord, they will also be playing the 1&5 notes plus whatever additional notes that make up the chord. Your sounds will blend together perfectly as your notes are integral parts of their chords and your two octave playing will enhance the overall sound. Likewise, if you are playing solo and accompanying yourself singing, the 1&5 of your power chord will compliment and back the melody you are singing.

– In One Finger Ukulele we tune to an open C5 power chord: CGCG.
– The root letter/note for every chord is found along the 4th string.
To play a proper substitute for any common chord, (Major, minor, 7th, minor 7th) simply find the fret matching the letter of the chord on the 4th string, bar that fret, and strum!

Playing Songs: The 1-4-5 formula
This is more stuff that you do not need to remember but is good to know: Most songs found in ukulele song books and played in uke clubs use the 1st, 4th, and 5th chords of a scale. These songs are referred to as… drumroll1-4-5 songs!

There are two other common components of the 1-4-5 song formula:

1) Minor chords: 1-4-5 songs also use the relative minors of the 1-4-5 major chords.  These are, in order, the 6, 2, and 3 minors. In the key of C, the 6-2-3 minor chords are Am, Dm, and Em.

2) The V7. The “5” chord in a 1-4-5 is often played as a 7th, so in the key of C you will commonly encounter G7.

In the key of C, the 1-4-5 chords are C, F, and G
And the 6-2-3 minors are Am, D, and Em.

Playing in other keys
It only makes sense that the concept of using the 1st, 4th, and 5th chords of a scale (and the 6m, etc.) works with all scales or keys. The challenge is to grasp the pattern. It’s not terribly difficult except when the pattern runs up too high on the neck and must start over again on the bottom. No matter the key, the 4 chord is always 5 frets up from the 1, the 5 chord is always 7 frets up, and the 6m is always 2 up, however the chords of the fretboard (and notes along the 4th string) start over at the 12th fret. Luckily you don’t want to play up that high on the neck anyway. Basically, it’s simple arithmetic but you must include the number zero. Zero is your open C chord.

The easiest key change to start with is the key of F. It’s a common ukulele key and the scale starts over at the bottom of the neck. In F, F(1)  is on the 5th fret, Bb(4) is up 5, on the 10th fret, and C is up 7, on the 12th fret, but the 12th is the same as 0, so you go back down to the open C. The 6m is Dm, on the 2nd fret, (6 being a full step up from the 5).

The chart above shows the chords in the key of C as well as in the other four common ukulele keys of F, G, D, and A: By strumming the color coded frets in the chart above, you have nearly all the chords you will ever need to play ukulele. Once again, with One Finger Ukulele you just play the letters by barring across the fret number indicated in the chart! Disregard the minor and 7th variations of the chords!

In short: Strumming the ukulele open (without barring any fret) results a C chord (and all common variations). Barring the 2nd fret gives you Dm (and all other common D chords). Barring the 4th fret gives you Em (and all other common E chords). The 5th fret gives you F (and all common variations). Barring the 7th fret gives you G (also G7 and other common variations). Barring the 9th fret gives you Am, etc. The 10th fret gives you Bb, etc.


One Finger “True” C7
Even though you don’t need to concern yourself with playing 7 chord variations, you can play a one finger C7 if you like. The position is identical to a regular C Major chord in standard GCEA tuning: one finger on the third fret of the first string. Strum this position then take your finger off and listen to the difference.

The Sliding Bar
Try sliding into a bar chord position from the fret below it. For example, slide into an F chord by beginning in fret 4 and sliding into fret 5 as you strum. If used strategically, this technique enhances some songs. This is demonstrated in the video when playing Dire Straits’ So Far Away.

Single Note Runs
A note or two picked between chords can be effective. It is especially fun to fret individual notes with one finger while strumming the open C chord. Start with the 2nd and 4th frets of the 2nd string then try others.

1+1 Licks and true 7 Chords
If your hands are strong enough, add a finger while barring. Start by adding your ring finger two frets above the bar on the 3rd string. Strum and alternate placing your finger down and picking it up on every other strum.

Next try placing your pinky finger on the 3rd fret above the bar on the 1st string. This position turns any bar into a true 7th chord version of the chord created by the bar.

How to play Dim* chords
Diminished chords do pop up now and then in ukulele music. They do not lend themselves to the “5 chord” philosophy of One Finger Ukulele as the 5 note is flattened in a dim chord. You only have three “One-Finger” options for playing a dim chord substitution. Both ignore the flattened 5 note:

1) Bar as usual on the proper fret that matches the chord letter, but only play a single root note on string 4.
2) Bar as above, but pluck/pinch only strings 4 and 2.
3) Mute the strings of the neck and strum a percussive “Zed chord.”

Let’s Play!
Here are portions of a few 1-4-5 songs that will work brilliantly with One Finger Ukulele. There are dozens if not hundreds more! There are also companion videos to each song.

The chord letter and variation are shown in black with the fret you bar in red next to it. For example, Am9 means you are playing the Am chord by barring the 9th fret. Got it?

The C7(1-3) indicates the One Finger True C7 chord discussed in the Embellishment section: Place finger on 1st string, 3rd fret.

Our Ukuleles Customized for One Finger Ukulele–Lots of Bang for the Buck!
To make it easier to play multi-chord songs in any key, we have customized two models of budget friendly ukuleles. We place D,E,F,G,A,Bb, and C markers on the near side of neck for quick location of proper chords. Use the spaces in between as sharp and flat versions of the adjacent chord letters.

In addition, One Finger Uke owners have access to an ever increasing online songbook with frets to play indicated in red as in the sample song below.

We re-string our tenor model with the proper string gauges for CGCG tuning and file the nut slot appropriately. On baritone, we condition a new set of baritone strings for optimal performance and add strap pegs. (You’ll want a strap when playing the larger baritone.)

Testing on tenor before diving in
If you’d like to experiment with One Finger Ukulele on a tenor before re-stringing it, you can do so with a low-G tenor. Here’s how:

From standard low-G GCEA tuning, tune the 4th string from G down to E (1 1/2 steps down). Tune the 3rd string from C down to B (1/2 step down). Leave the 2nd string tuned where it is at E. Tune the 1st string from A up to B (1 full step).

This results in the tenor being tuned to an open E chord. The patterns for playing 1-4-5 songs will be the same, 4 chord on the 5th fret, 5 chord on 7th fret, 6m on 9th fret. This will only work for solo experimentation as I doubt that you will encounter anyone else playing a song in E, put you’ll be able to experience the concept.

In Summary

1) One Finger Ukulele is a way of re-tuning your uke so that you can play rich, full, alternative chords with only one finger shape.

2) One Finger Ukulele requires a low, wound 4th string.

3) You will be tuning to an open C5 chord as follows, (from lowest/4th string): C-G-C-G. Since all common chords (except diminished) use a common 1st and 5th notes, barring any fret will give you a proper alternative chord based on the root note of the 4th string, that will match any form of that letter chord. Since you will automatically be playing the 1-5 notes in two octaves, it will sound good when played with others or when accompanying your own singing.

4) One Finger Ukulele works best and is easiest to play on a baritone. You don’t need to change strings and the longer neck gives you more room for Am, Bb, and other chord positions up the neck.

5) With tenor* ukes, you must move the 3rd string to the 2nd position and install new 3rd string in the range of .029-.031 and a new 4th string in the range of .039-.041. We sell the required new strings in our uke store or you can purchase them yourself.

*One Finger Ukulele is not feasible on ukes that are smaller than tenor.

Those are the basics! But there’s lots of important info above, so if you skipped to here I’d go back and at least watch the first few videos.
