Therein lies the confusion, I meant "CM7, Cm7 and C7 are major, minor, dominant, respectively".

My bad.

Using shorter forms (like delta, plus, degree etc) isn't about being lazy. It saves time, ink, and space. If you've got 4 chords to a bar (all with extensions) you have to be able to fit them all. I've read of plenty of charts where the chord names were overlapping (harder to read and more irritating than any standard notation). Aside from that, obviously the more you can fit on a page the better since it allows you to write the score out with less pages (if you've ever had to use 2 music stands or worse, do page turns in the middle of a performance you understand why this is important)

Like HaVIC said it does come down to preference. I had a jazz theory professor who wouldn't let us use delta and degree in the same score since a sloppily drawn maj7 turns into a dim so easily.. and when you hear the two together it's not exactly pretty.

It becomes the infamous major 7 (#9, #11, 13) chord, and actually, depending on the context, can sound pretty hip. Duke Ellington loved ending on this chord. Jobim uses it sometimes in his tunes. There's a lot of interesting history that goes along with the chord - classical music calls it the "auxiliary triad" - a triad a half step below the tonic resolving to the tonic. Often guitarists/pianists will play this as the first chord of Misty resolving it to the tonic in bar 2. You might voice it as B/C, or Co7(maj7), but if you want it nice and spicy, do the maj7(#9) thing.

But, you know, if you want to be all lame and write clearly, go right ahead. The best things often come from mistakes.

I found this in the net!
- sign=applied to chord names or numbers: indicates a minor triad, for example the notes C, Eb, G. C-7 means a C minor 7th chord
