1. A guitar with all 6 strings (acoustic or electric will do).
2. A guitar tuner (I recommend a Snark clip on tuner, available from $15 to $20 USD) or an app that will work as one (I recommend GuitarTuna - it's free)
3. A few guitar picks.
4. A way to view the music and materials I send.
5. A good seat without arm rests, ideally one in which the learner can sit upright with their feet touching the ground.

Optional, but nice:
1. A good, sturdy music stand. One with a solid back is best. These often cost $25 USD or more.
2. Print-outs of the music and materials I will send, as well as a folder or binder to keep them in.

I pull my music selections most often from popular music (often just whatever music the student has expressed interest in). For younger students by default I avoid anything explicit, but for teens my default is to allow them to decide whatever music they'd like to play. If there is any particular content you'd like me to avoid with a student, please communicate that to me.
