The touch and feel of the keys is so piano like and is also graduated relative to the different weight of the strings from bass to treble.
So I have purchased Book 1 of John Thompson's Modern Course for the Piano and have started the process of teaching myself. As I already read the treble clef fluently it is mostly a matter of becoming more familiar with the bass clef and to develop a sound technique for the instrument. I will go and get lessons to ensure I am staying on the right track technique wise and I am really keen to particularly develop good sight reading skills as I have for the guitar. I have high expectations as I usually do with everything I start and look forward to playing Beethoven piano sonatas some time in the future. Laboriously worked my way through the opening of the Pathetique yesterday, the music sublime, the playing? Umm, well, more practise required!
