Why F7?

Why this F7? Why not a C7, E7, G7 , or other open position seventh chords that these core chords are based on?

This F7 is based on the Open Position E7 and the only one of the E7, C7, A7 and G7 open position chords that the Big Six Core Seventh chords, in their first position, first fret (1) transposable versions are a natural letter chord name. That way you don't have to worry about Enharmonic Equivalents such as C#7/Db7, A#7/Bb7, or G#7/Ab7. An yes I know that there is E# - however that is very rare.

SeventhChords-fret1

Beyond Basic Open Position , Basic Movable Form Chords and Core Set Of 4-part Contemporary Chords there are just too many chords shapes too memorize. Learning the principles of how chords are constructed and the ukulele fingerboard are the way to go. Then you can create more advanced chords like 9#11, 7#5-9, 13b5, 7+9 on the fly as needed.

Seventh chords are the chords that have the most possible variations. 9th, 11th, 13th, b5, #5, b9, #9. And, combinations of the same.
