The TuneUp System by Stephen Colley is GREAT for pitch relations, chords, and training your ears. I use that daily. There is also a series of cd accompaniments for the Rochuts that are fantastic and really fun. The Schwartz editions are available in all volumes through Hickey's for about $18-20 per. The new HipBone Twenty Minute Warm-up Routine with Mr. Pokorny demonstrating the exercises with interesting electronic accompaniment and then with the accompaniment alone looks very promising and VERY challenging!

Hope this helps,
