More than Chords and Scales
A few very talented self taught musicians have been able to become legendary performers, however for most people, the most reliable path for quickly becoming a proficient player is paved with (one on one) private lessons.
No matter what style you want to learn to play from Bach to Rock, the basic foundational principles are the same, even for singers. The greater your knowledge is - the better your "chops" will become.**
(And a-grinning too.) Playing music is about creativity, passion, and expression. Sometimes, the best way to unlock your creative side and take it to a new height is with a measure of guidance, accountability, and the gentle challenge from a more accomplished musician.
