I'm trying to figure out how best to write a lead sheet for a player given a certain chord progression as an example:
shortchord.org/RqxRx (disregard the automatic names this app gives to the chords)
It seems like I have two options for how to write chord symbols for this progression, with the difference being in how to represent the second chord.
I can see naming this progression in terms of chord function, where the second chord is a secondary dominant of Dm7, as:
Cmaj7 | A7b9/C# | Dm7 | G7
( I | V of ii | ii | V )
Or, I can see naming the chord to be more accurate about which notes this specific voicing contains:
Cmaj7 | C#dim7 | Dm7 | G7
Both describe the rising chromatic bass note from C to C#, but one describes the dominant relationship, while the other specifies the dim7 chord structure without adding the implied A.
My question is, which is easier for a player to understand? Or, at least, what is the difference between what's communicated to a player in each approach?
