Just discovered this great website: thank you for creating it! Book ordered and looking forward to its arrival. What do you — and fellow students — recommend for practising in different keys? My instinct, each time I start a new exercise, is to work through all twelve keys. Feels like, if my fingers are really to know what they're doing and be able to improvise smoothly, they need to be able to play confidently no matter what key I'm asking them to go to. But it's slow doing everything twelve times — especially in some of the lesser-visited keys (F# ...). Thanks for any advice ... Adam
