Heard a few good things about Essential Elements so thought I'd give it a try. Been using it about a month.
For someone such as myself (ie still in the early stages) I think its good. I can see the benefits of using it with a school/private/band teacher, but using it on my own seems to work pretty well too. Steady learning curve, sufficient information and some nice little play along tunes.
Anyway, I just thought I'd share my experience with it. Feel free to share your thoughts/experiences.
P.s. I thought the listening library quite good too. I have very limited experience with this type of music but a few days ago I listened to them, and I really "listened" and thoroughly enjoyed it.
