Learn a new Ukulele chord every day of the year. The chord for February 22nd is F#m7b5.
Today's chord, F#m7b5 is the first chord, if using a Low G, C Tuning, where all the notes are within one octave – a Close Position chord. When using a High G
' C Tuning, all the notes are in a close position, within one octave. It's often misnamed as a D9.
Today's chord might also be called D9 and/or — the list can go on and on with more and more obscure chords. It all depends on the harmonic situation and the chord's harmonic function that it is being used in that determines the name of the chord. A bass player can change the function of a chord with the bass note they play, as that can be perceived as the root or letter name of the chord. Bass players have extreme harmonic powers, and they can use it for good or evil.
What's really useful is you don't have to learn a new fingering or voicing for other same shape chords when they come up. If you recognize the chord as another chord that is common in your repertoire, you can re-use it in the current context.
Here is a cool, fun exercise: *7alt —alt
, short for alteration. This is telling you that you are free to create the seventh chord with any upper partial extension ( 9th, 11th, 13th) and any alteration(s) that you would like: ♭9, ♯9, ♯11, ♭5, ♯5, ♭13. An example would be C7alt, the base C7 is C E G Bb – the 1 3 5 ♭7. You're free to add D♭, D♯, F♯, G♭, G♯, A♭. So your possible notes available are: C D♭ D D♯ E F F♯ G♭ G G♯ A♭ B♭. Notice B, the major seventh is NOT available. So, bottom-line is — if your chord does not contain a major seventh, you can justify every other note you are playing.
So when it comes to that dominant seventh chord or tri-tone sub resolving to what would be its I chord. And, if you don't know what to play, grab any shape and go for it. You have a 1 in 12 shot of hitting that major seventh, which would be really hard to justify a B7alt — B is the major seventh.
Including the 3rd and b7 goes a long way in keeping the intent of the base 7th chord. So, you have tow more noes to muck around with — BUT NOT the major seventh. Walk over to any piano and play the two-white keys together, and you get the why.

Although additional fingerings are possible for many chords, fingering for any given chord depends on the science of how our fingers work and on the harmonic context the chord is being used in—what was the previous chord, and what's the next chord? The goal is to play all the notes right behind the frets when possible. Remember, longer fingers can reach the lower strings better, and finger two can stack on finger three, and finger three can stack on finger four.- 4 3 2 0
