Must Have Resource
The first thing I bought from Truefire was a CD and it came it the mail. I think it was in the 90's. The new digital stuff is amazing. I have a bunch of courses that I have bought over the years. All of those courses are available for my use anytime. I use the desktop app and the online website mostly.
The variety of educators and styles makes finding something to work on quite easy. I am a hobby player that plays at home. Truefire has been a go to source for music education for a long time. Affordable and consistent.
