If you have never had lessons, or need a quick refresher from your childhood, I use the Alfred Adult All-in-One Course. It puts Lesson, Technique and Theory all together. Learning moves along quickly, focusing on chords.
You will be responsible for purchasing all the materials needed.
Lessons will take place every other week unless requested otherwise. Daily practice is encouraged. The more you practice, the faster you will progress.
The cost is $30 per 30-minute lesson for Level 1, $35 per 30-minute lesson for Level 2, and $40 per 30-minute lesson for Level 3.
If you have taken 5+ years of piano instruction, the materials used will vary with the student.
The cost for 5+ years of piano instruction is $45 per 30-minute lesson (for non-classical music) and $50 per 45-minute lesson (for classical music).
