A# Lydian — Viola

A# Lydian is 7 notes to the octave (modes family), drawn here along the Viola's CGDA strings with every A# named, so home is findable from any finger.

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.

Because the strings climb in fifths, one hand position covers a wide span of the fingerboard — four fingers, a fifth of range per string, and the same finger pattern repeating across every neighbouring pair. Learning a scale here is mostly learning WHICH position it wants and where the shifts fall.

Open-string drones: every one of the Viola's 4 open strings belongs to A# Lydian — the C string (the second), the G string (the sixth), the D string (the third) and the A string (the seventh) — so they can ring beneath the line as a fixed reference.

The D string is a chord tone of the A# tonic triad, so it stays consonant against every degree of the scale.

Play it slowly with a long bow, one note to a stroke, and listen for the notes that pull sharp or flat against the open C and A. Intonation on this instrument is a conversation with the open strings — nothing on the fingerboard decides it for you.
