A Locrian Scale — Notes, Chords & Free MIDI
The A Locrian scale is A, Bb, C, D, Eb, F, G. Free MIDI download, with the chord built on every degree of the key — no sign-up.
The one mode with a diminished tonic chord: both the second and the fifth are flattened, so the home chord cannot settle. It is a scale that refuses to resolve. In A Locrian the notes are A, Bb, C, D, Eb, F, G, written with 2 flats (Bb, Eb). Its parallel major is A Major. The interval that gives it its sound is the b5 above the tonic. This page presets the scale tool to A Locrian — play it, or download it as MIDI with or without the chords.

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 A Locrian, so the preview and the download both start on A4 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 A Locrian reference lane earns its keep fast: with A, Bb, C, D, Eb, F, G 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.
