Open Position Chord
An open position A major chord can be played with any finger. All depends on the context of its use. Typically played with either fingers one and two or two and three.
Movable Form Chord
Movable Chord Forms
Movable chord forms are chords containing no open strings. These chords are transposable to different keys by moving the chord form the same number of frets up and down the neck.
Each movable form is based on a common open position chord. These movable forms allow you to play chords not found in the open position.
Movable form chords allow you to play in any key and transpose chords, progressions and songs to any key. From basic movable form chords more advanced chords can be created.
The functional range of a movable form chord up the fingerboard of your ukulele depends on the ukulele's size (soprano, concert or tenor), the number of frets to the body (10, 12, 14, etc) and whether you have a cut-away for access to higher frets. Not all chords can be transposed a complete octave (12 frets).
Movable form chords can be used along with open position chords. As you learn more movable form chords you'll have a variety of alternate voicings for any given chord.
Movable form chords can be transposed up and down the fingerboard using the root of the chord and a transposition chart.
Transposing Movable Form Chords
These lessons use the root of a chord to transpose to different keys.
Determine what string the root is on or would be on if not present in the chord's voicing.
Chord Transposition Chart
This transposition chart can be used for any chord where the root, or letter name of the chord is on string A.
The root is on string 1, the A string.
Use the Root or implied root of the chord to transpose to different keys.
A larger sized transposition chart is available in my book Ukulele Chords. This is the book these chord lessons are based on.
Chord Tones - A C♯ E G
The chord tones of an A7 chord are the 1st, 3rd, 5th and flatted 7th scale degrees of the A Major Scale ( A B C♯ D E F♯ G♯ A' ) or A C♯ E G
- 1 - the Root or letter name of A7 is A
- 3 - the third of A7 is C#
- 5 - the fifth of A7 is E
- b7 - the flat seventh of A7 is G
Misnamed 7th Chords
Seventh chords are often misnamed as dominant seventh chords.
Whether a chord is a Dominant chord refers the its harmonic function within the chord progression — how it's being used. If the chord is functioning as a true V, or five chord in the progression it can be called a dominant seventh chord. If not it's simply a seventh chord and doesn't or shouldn't have any harmonic designations added to its name. We don't call other chords a Tonic Seventh, Sub-Dominant Seventh, or Medient Seventh.
For more information on dominant seventh chords see my UkuleleLesson: When Is A Dominant Seventh Chord Not A Dominant?
Chord fingering is dependent on several factors. The chord your on, the previous chord, the next chord, your hand and fingers. All chord fingerings shown are recommended fingerings and not mandatory. Most chords have alternate fingerings dependent on the context. The same chord might even be fingered one way in one part of a song or progression and an alternate fingering in another part.
The seventh chord form is a core chord voicing for creating additional 4-part chords. From core chords other all other 4-part chords can be derived. There is a minimum core set of six 4-part chords to get started with. There are: 7, maj7, m7, m7b5, dim7, 7+5. A complete core set of eleven is needed to really explore 4-part chords. This set of eleven include the minimum set of six as well as: 6, m6, mL7, dimL7, +L7. To throughly explore these core set of chords and their possible extensions, upper partials and alterations see my book A Guide to Advanced Chords for Ukulele
Raise the third (3) of a seventh chord one fret.
A 9th chord is a 5-part chord.
For a 5-part 9th chord, the root is implied and displaced for the ninth. Optionally the 3rd of a 7th chord can be lowered two frets (a whole step) for 1 9 5 b7. This really works if you have already played the chord with the third present and establishing the color of the chord.
To create a ninth chord raise the root of a 4-part chord two frets. This applies to a 7th, maj7, m7, 6, m6, m7b5, etc... Most all 4-part chords can be turned into ninth chords. For a 7th chord this would be a 9 3 5 b7.
This same process can be applied to a triad by raising the root two frets. For these chords they are typically called add2 or add9 chords.
Chords are pretty flexible and can be implied by containing the notes of the chord that make it different then another chord types with the same root. Take C and Cm, C is C E G and Cm is C Eb G. The third of the chord the E or Eb is a color tone and is responsible for making a major chord different sounding then a minor chord with the same root.
Take lesson one's practice progression and make all the chords a seventh.
Blues Practice Progressions
The Blues are at the heart of all American music. From the Rock, Country and Folk to Jazz. Making the form a great way to get a handle on this weeks chord.
Blues in the key of C
Blues in the key of F
Blues in the key of Bb

Just browsing over both books, they look fantastic! I'm a guitarist and uke player for over 25 years and was thinking about writing a ukulele book but you've already written what I think are the best, most comprehensive and thorough books I've ever seen for the instrument. I just might end up buying every book you've written and I'll be giving my highest recommendation for your books to my friends and students. Thank you so much for taking the time to write such great books! — Peter Rhee
Aloha, Curt, All I can say is WOW! What you have accomplished is simply incredible! All the best — Glen Hirabayashi, The Aloha Boys
