Most of my pro playing was done with guitar , so my thinking is based on scale and chord comping.

1-G7 to C major. V7 to I (Scale steps) This is the most used chord progression.

2-F7 or F to G7 to C ---- IV7 or IV to V7 to C

3-Orginal chords -- Singer stops on a C note -- one silent measure following preceding to the F7 chord. Silent measure -- 4th beat F#7 medium volume to F7 stronger volume, singer comes in at this point.

How simple, but we are going to build on this thinking.
Substitute Dm7 G7 for G7 In scale steps: IIm7 V7. You can also sub. Em7 for a C chord. Notes in a C maj9th – C E G B D notes in Em7 E G B D. a good sub. when used in the right place.
Original chord; C //// G7 //// C ///

Sub. Voice is going to hold a note from the first beat until the next C chord. C // Em7 / Ebm7 / Dm7 // G7// Voice begins to sing again on the C chord. Scale Steps: I// IIIm7/ Ebm7/ Dm7// V7// C////

I am using songs from Big Band like Misty or The Lady is a Tramp for my example – it is different for other types of music. This study leads to understand how to reharmonizing all or part of a song. How scale modes are formed. Solo lines both as arpeggios and altered chords, and much more like how do I comp.

If there is interest I will post simple short examples.
Thank you for starting this comping post Bernie, its going to be interesting.

Wow, I just listened to Kansas City, and again Donny has demoed with a pro sounds like.
