You'll hardly find a jazz fake book that does not use triangles somewhere or always for M7, take a look at Aebersold, Hal Leonard, Sher, etc. It's pretty widely accepted norm when you dont want the dominant 7th form, in jazz generally the 7th is always assumed flatted unless there is M, Maj or a triangle.
The "o" with a slash through it now, that is less widely known, most people prefer to see "m7b5" instead, that one IS an abomination because so many people dont notice that slash and play a diminished chord mistakenly. The "o" with no slash for diminished and "+" for augmented 5th forms are widely accepted though. -- View this message in context: http://www.nabble.com/triangle-chord-notation-tf2042072.html#a5640226 Sent from the Gnu - Lilypond - User forum at Nabble.com. _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user
