Thanks for the reply High Score.
I'm not stuck as such.The improvisation section has me a little worried if i'm honest.The performance section has bass patterns which i'm fine with in all keys.The improv section in the RGT book has backing music CD provided and you make up a bassline to suit the piece following a given chord chart which can have major,minor,major7,minor7,dominant7 etc chords(you're expected to play root,3rd,5th and 7th where appropriate) but its in one given key.Do they throw you a curve ball for the exam with a different key from the book or do they use the same one ??
Sorry to ramble on but that's the best way i can describe it.
Cheers,
Pete.
