The Key of B — Lap Steel

The tonic, subdominant and dominant chords, and what this chair plays across them.

B major harmonises to B – C#m – D#m – E – F# – G#m – A#°; B minor to Bm – C#° – D – Em – F#m – G – A. Most of the country repertoire in this key lives on three of those chords — the tonic, the subdominant and the dominant — plus the relative minor when a song wants one darker turn.

The lap steel chair carries a held chord under the singer — the bar laid across the strings, slid into place and left to ring. Its strings are already tuned to a chord, CEGACE, so there is no shape to make — only a fret to lay the bar on, and the slide that gets it there in time for the change. Every diagram below is a straight bar or a short slant, and a quality this tuning cannot spell that way is marked instead of drawn.

Learn the tonic-subdominant-dominant grammar in B until your hand goes there without asking, then add the relative minor, and most of the repertoire in this key is already playable.
