Tune Up in Fa#

Tune Up in Fa#

Miles Davis's etude-like composition strings together three consecutive ii-V-I sequences descending by whole steps, making it a definitive workout for Bebop Major, Dorian, and Mixolydian in three different key centers in quick succession. The logical harmonic structure makes it an ideal teaching piece, but musical phrasing across the key shifts separates good players from great ones. The bridge offers a moment of tonal stability before the sequence repeats.

Tune Up in Fa#

F# major pushes guitarists into full barre territory at fret 2 and beyond. No open chords exist naturally, but the key rewards advanced players with dark, powerful voicings. Common in metal and progressive rock where low tunings bring it closer to standard pitch. F# is a intermediate-advanced-level key on guitar because the open B string is the 4th scale degree and the open high E is the minor 7th, both usable as color tones. Expect to rely on barre chords throughout, which builds hand strength and unlocks the entire fretboard.

Voice Leading

The bass line moves through G# to C# (ascending perfect fourth), C# to F# (ascending perfect fourth), F# to F# (ascending unison), F# to B (ascending perfect fourth), B to E (ascending perfect fourth), E to E (ascending unison), E to A (ascending perfect fourth), A to D (ascending perfect fourth), D to F# (ascending major third). The root motion by larger intervals (fourths and fifths) gives each chord change a strong, decisive character. When the progression loops, the bass returns from F# to G# by whole step.

Scales for Improvisation

F# major pentatonic works because every note is either a chord tone or a safe passing tone — there are no avoid notes. For soloing, this means you can play freely without clashing. Over dominant seventh chords, F# Mixolydian adds the flat seventh for an authentic blues-rock edge.
