Hi everybody
I'm a classical guitarist (grade 8), and I now have a real desire to develop some basic piano skills quickly. In particular, I would like to be able to sight read basic pieces.
In some senses I'm a complete beginner because I've never played a keyboard instrument before, but on the other hand I'm not because I'm very familiar playing and reading multi voiced music with my guitar.
Can anyone recommend a good self-tuition book or do I need a teacher? How quickly can I expect to get up to a competent level if I can spend half an hour day on this? Any advice would be appreciated.
Wouldn't it be great if we could all 'speed learn' an instrument! Like you, I am a Guitarist(Grade 8) but play other instruments, piano amongst them. I self-taught myself piano 20 years ago but couldn't get beyond Grade 4 level. I am now having lessons and can see some light at the end of this very long tunnel.
Find yourself a good teacher who acknowledges your experience on another instrument and will understand that you might need to approach things in a different way to someone with no musical experience. I speak from experience.
I think I know of a teacher who is based in London and is a Gutairist and a Pianist. PM me for further details.
You could start by buying the Alfred books for Adults which use a 'chord based' approach in the left-hand. You will quickly find that you can play right-hand much more confidently than your left-that is the frustrating part!
