I recently hit the two year mark of being part of Tony's Acoustic Challenge and I continue to look forward to playing and completing the daily challenges everyday. When I first started this program, I could play basic chords and generally used 1 - 2 strumming patterns. I never went past the fourth fret of the neck. I would barely ever use my pinkie finger on the neck. Within the first 30 days of the program I was already playing further down the neck, playing individual notes, using a backing track to improv, and learning blues shuffles. Since then, I've learned 3 alternative tuning patterns, how to use a slide, multiple songs, guitar solos, scales, improv using scales, multiple strumming patterns, palm muting, and so much more. I play more consistently than ever before. My finger strength, pick accuracy, and fretboard knowledge improved dramatically.
