Whatever the film, from Harry Potter to James Bond, you can get Free Sheet Music online.
Although it is possible to try to learn to play movie scores by ear, or even to learn the latest chart hits, it’s ideal to have the music written down to follow and learn.
Popular music, be it rock, pop or other sub-genres is often annotated using guitar tabs. This avoids the need for the musician to be able to “read music”, rather he just has to follow the tablature. Such tabs can however be fairly inaccurate and are usually used to supplement the guitarist listening to the piece of music and then playing back what he has just heard.
Sheet music can prove fairly expensive, although when bought in a book with other songs, this can keep the price down.
