Lap Steel: Scales for a Country Fill

Pick a root and one of 24 types and see it as it lies on this chair's neck, roots marked throughout. Three of these carry most of the repertoire; the rest are for the song nobody warned you about.

A lap steel fill glides between the singer's lines, often on two strings at once, so a scale here marks the frets where the bar may come to rest — the glide carries the line, and the scale keeps every landing note inside the song's key.

A fill is not a scale played straight through. It is a handful of notes pulled from one, timed to land before the vocal comes back in — which is what a scale map is actually for.
