i cant immagine actually reading a chart off of an iphone.
Neither could I. Until I had to. It worked! Wouldn't want to do it all night, but its better than "Gosh fellas, I wish we could play that song but I don't know it and don't have a chart."
And as far as the "purists" out there who say that any chart-oriented gadget or tool is a sign that the jazz apocalypse is upon us, that we should all either memorize the tune or get off the stage, well, it just gets me thinking of all the teachers out there who refuse to use charts when teaching for fear of ruining jazz because it was only meant to be learned by ear.
I'm a hard-working part-time player. I can read music and I've taken the time to learn to play jazz, but I didn't go to music school and I have no desire to become a full time musician. Heck, I don't even play upright bass! But I know how to get gigs and have been able to play many jazz gigs despite my limitations. If it weren't for this app and other helpful tools on the internet, I would never have been able to enjoy the many hours on stage playing great music with talented musicians.
OK, rant/thread de-rail over.
I use this app all the time. I love the changes used on these tunes from the library available in the iRealB forum and have played entire gigs with singers who use non-standard keys using just the charts I print out from this app. Yes, it would be nice to have the melody as well, but for $20, this app does amazing things. Great to use for silent rehearsals as well, goes without saying.
