Banjo Fills With C# Lydian
Where C# Lydian lies on Banjo's fretboard, and the fill it feeds.
C# Lydian runs 7 notes to the octave. Below it is laid onto this chair's GDGBD fretboard with every C# marked, because what a fill needs mid-song is not the pattern — it is where the root is when the chord changes under it.
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.
A banjo fill is usually still a roll, with the melody notes pushed to the top of it — the scale says which notes the fretting hand can put there, while the open strings and the high drone on the short fifth string keep ringing underneath.
Play it slowly against the audio until the shape stops being a shape, then take it to a song in C# and let the melody pick its own notes out of it.
