You’ll need to have an instrument to practise on at home as soon as lessons begin (or regular access to an instrument elsewhere).
An acoustic piano or quality digital piano (with weighted keys) is ideal, of course!
However, I understand that it might feel like too much of a financial commitment to purchase this in the early stages. So I am happy for a keyboard to be used to get started- but realistically only for the first couple of months. Otherwise it is a bit like trying to play tennis with a badminton racket!
I am always happy to advise new and prospective students on instrument options.
Lessons at my home take place on a superb Schimmel upright piano which everyone loves to play!
