C# Lydian — Cavaquinho

C# Lydian is 7 notes to the octave (modes family), drawn here across the Cavaquinho's DGBD strings with every C# marked, so home stays visible from anywhere in the pattern.

Major with a raised 4th (#4) — dreamy, ethereal, and floating. Often called the brightest mode, with an otherworldly suspended quality.

Heard in: Film scores, progressive rock, jazz — Joe Satriani's "Flying in a Blue Dream", John Williams, Steve Vai.

Four strings tuned DGBD put a scale somewhere honest and a little cramped: two or three notes to a string, no spare string to hide on, and every open pair climbing rather than doubling back. These maps mark every root so the top voice never loses home mid-run.

Practise it as a fill, not a ladder: pick four of its notes, drop them into the rests of a batida cell, then slide the same four to the next position. That is how this instrument actually uses a scale — a top voice riding above the chop, not a run played alone.
