I'm a guitarist and I'm working on working on learning Lee Morgan's trumpet solo on Art Blakey and The Jazz Messenger's' "Moanin'" and I've noticed several notes with either "1/4" or "1/2" written above the note. I'm guessing that this tells the soloist to "bend" the note upward either a quarter or a half step. Can anyone tell me if that is the case? Also, if that is what's going on, is the note that's written out where the note ends up at, or is it the note that is played and then bent upwards? In other words, using the solo as an example, the third note in the tenth measure is a D (concert C) and "1/2" is written above the note. So does the soloist start at D and wind up at Eb, or does he start at C# and end up at D?
Here's part of the solo:
