If you are interested in taking grades on the guitar I teach two syllabuses, Rockschool for electric guitar and the RGT Acoustic guitar grades. I teach both from grade 1 through to grade 8 and have a 100% pass rate.
I teach students of all ages grades and it can be a great way to measure progress and have something to aim for. Both Rockschool and Acoustic grades are similar in that the grades cover a mixture of the following;
- Pieces to play (3 for rock school and 1 for RGT)
- Aural tests
- Playing unseen material e.g sight reading
- Rhythm tests
- Knowledge of the instrument and basic music theory
It therefore does help students become a well rounded musician. I tend to teach grades alongside ordinary songs to help relate learning to songs a learner knows. It also offers excellent practice and performing something in front of someone else.
