Recommendations on how to go about transcribing a song to notes, and how to determine 1st / 2nd parts? A friend of mine said I could try to work on a song to play with his group where he would do the 1st trumpet, me the 2nd trumpet. The song la sonora dinamita - Carmen I have a few notes down, but looking for suggestions on how to figure out the notes. So far unfortunately the only notes I have done are because he came the first few but I would like to figure out the entire song. As well as how you normally take the first part and work out a 2nd part from it?
