How to play C# Locrian bb3 bb7 on guitar
Find the root first: C# is at fret 9 on the low E string and fret 4 on the A string. The blue notes on the diagram are every C# on the neck; the gold ones are the rest of the scale's home chord (𝄫3, ♭5, 𝄫7), the safest notes to land on at the end of a phrase.
Learn it one box at a time. Position 1, the E shape, sits at frets 9–13. Once it's under your fingers, move to position 2 (the D shape) and play the notes the two boxes share, then keep going up the neck. After all five, the scale joins up into one pattern across the whole fretboard.
