02The coach

Feedback that
means something.

Nice run through Seven Nation Army. Your E string is clean and you nailed all 9 notes. Watch your intonation on the C, you are consistently about 18 cents flat there, which suggests your index finger needs to sit closer to the fret. One tip: slow the tempo to 60% and focus just on that C note until your muscle memory locks it in.
