Standard tuning (EADGBe). Click a string to hear its reference pitch.
Vertical lines are strings (low E on left). Horizontal lines are frets. Colored dots show finger placement. x = muted, o = open.
Practice switching between two chords slowly. Keep fingers close to the fretboard. Speed comes from muscle memory, not force.
Down strums on beats 1-2-3-4. Add upstrums on the "and" between beats. Keep your wrist relaxed and let the pick glide.
Use your index finger flat across all strings. Roll slightly toward the nut side. The F chord is the gateway — master it and you unlock the whole neck.
I-V-vi-IV appears in thousands of hit songs. Learn it in C (C-G-Am-F) and G (G-D-Em-C) to cover most campfire requests.
15 minutes daily beats 2 hours once a week. Warm up with chord changes, practice a song, end with something fun.
