Gb Blues Scale — Notes, Chords & Free MIDI

The minor pentatonic with a flattened fifth wedged between the fourth and the fifth — the "blue note" that gives the scale its ache when it is bent or passed through rather than sat on. In Gb Blues the notes are F#, A, B, C, C#, E, written with 3 sharps (F#, C#, G#), plus C written in. Gb and F# are the same pitch, and the notes are written from F# here because spelling them from Gb would need double flats. Its parent scale is F# Minor. The interval that gives it its sound is the b5 passing tone. This page presets the scale tool to Gb Blues — play it, or download it as MIDI with or without the chords.

The notes of the Gb Blues scale

Gb and F# are two names for the same pitch. The notes below are written from F#, because spelling this scale from Gb would need double flats — the same reason sheet music writes it that way.

Where the Blues scale is used

blues, rock and roll, soul, funk and jazz solos; the default vocabulary of guitar lead playing.

How it works

Choose a root note and a scale, and this tool builds a MIDI file containing the scale played ascending and descending in quarter notes. Enable diatonic chords to also include the triad built on every degree of the scale — a quick way to hear which chords belong to a key. Press play preview to hear the exact notes before downloading. This page arrives preset to Gb Blues, so the preview and the download both start on F#4 and climb through the scale from there.

What can you do with a scale MIDI file?

• Drag it into your DAW as a reference lane while writing melodies.
• Learn unfamiliar scales — modes, pentatonics, harmonic minor — by seeing them on a piano roll.
• Feed it to arpeggiators or samplers that expect incoming MIDI.

A Gb Blues reference lane earns its keep fast: with F#, A, B, C, C#, E laid out on the piano roll, one glance tells you whether a note in your melody belongs to the scale or is a deliberate colour tone.

Frequently asked questions

What notes are in the Gb Blues scale?

The Gb Blues scale contains 6 notes: F#, A, B, C, C#, E. Measured against the major scale that is 1 b3 4 b5 5 b7, and the step pattern is W+H W H H W+H W. The MIDI file plays them ascending and descending in quarter notes starting from F#4.

Why does the Gb Blues scale have no chord for every degree?

Gb Blues has only 6 notes, so stacking thirds on each one does not produce a triad on every degree the way a seven-note scale does. Players treat it as a melodic vocabulary over chords borrowed from its parent scale instead.

Is this Gb Blues MIDI file free to use?

Yes — the download is free, requires no sign-up, and the generated MIDI is royalty-free for personal and commercial projects. A scale is not copyrightable in any case.

How do I use the scale MIDI in my DAW?

Drag the downloaded .mid file onto an instrument track in any DAW (Ableton Live, FL Studio, Logic Pro, Cubase, Reaper, Bitwig, Studio One). It appears on the piano roll as regular notes you can edit, transpose, or feed into an arpeggiator.
