I have the previous book (or 100 rather than 100 more) and love that as well. Songs (mainly well known pop songs) are graded in difficulty from one to three stars so you can easily pick out the simpler ones to play. I haven’t got past that stage so can’t talk about the more difficult ones! However, having had a saxophone for 6 weeks I can play a few tunes that my wife recognises. Bear in mind that I am 60 and have never before read music (looked like a spider walking across a page, had no meaning to me at all) or played an instrument. Really good book
