Piano students need a real piano or piano keyboard. If you already own a piano, you should have its condition checked by a professional tuner. It is very important that the mechanism is in good order, and that the piano can be tuned and maintained at correct concert pitch.
NB. Suzuki Teachers are involved in ongoing training and each teacher will have completed one or all of the 4 levels of training. It is recommended that you check with the teacher which levels they have completed.
