I have been playing around a year and am a fluent reader having played other instruments, but need help with organising a manageable practise routine. I want to spend about half an hour a day practising and know that I have to do long notes, tongueing exercises and scales/arpeggios as part of this, but need a structured course or book or something to keep me motivated. Also I want to learn to be more flexible and improvise a bit more. I am supposed to be joining a band where i am expected to construct my own parts and really don't know where to start! Can anyone recommend anything?
