A Tcherepnin Hexatonic Scale — Notes and Intervals
The A Tcherepnin Hexatonic scale is a perfectly symmetrical six-note scale alternating semitones and minor thirds, with only four unique transpositions before repetition. On Piano, the notes are A, Bb, C#, D, F, F#. Despite its economy, it contains both major and minor triads, giving it surprising harmonic richness for ostinato patterns and crystalline orchestral textures. Commonly used in Classical, World, Experimental, Film Scores. Notable players include Alexander Tcherepnin. Use over both major and minor triads built on scale tones. The symmetrical structure allows pivoting between tonal centers spaced a minor 3rd apart. Effective over ostinato patterns.

Origin & Background
Created by Russian-born composer Alexander Tcherepnin (1899-1977) as part of his personal compositional system. The scale's limited transposition properties place it alongside Messiaen's modes, though Tcherepnin developed it independently. He used it extensively in his piano and orchestral works.
How to Play A Tcherepnin Hexatonic on Piano
On piano, the A Tcherepnin Hexatonic scale uses 3 black keys. Start with your thumb on A and use the black keys as landmarks for consistent finger placement. Standard major or minor fingering patterns apply.
The A Tcherepnin Hexatonic scale contains both sharps and flats (2 sharps, 1 flat), which is common in altered and exotic scales. This scale does not follow a traditional major or minor key signature, so reading from sheet music may require accidentals.
Practice Routine — Exercises for Playing
Set a metronome to 100 BPM and play the A Tcherepnin Hexatonic scale in groups of four notes, shifting the starting note each repetition. This builds muscle memory across the entire scale range. After a week, try improvising short 4-bar phrases using only these notes.
Experiment with simple two-chord vamps rooted on A to let the characteristic intervals of the Tcherepnin Hexatonic scale come through clearly. This scale is especially effective in film scores contexts.
Piano Tips
On piano, practice the A Tcherepnin Hexatonic scale hands together in contrary motion (one hand ascending, the other descending). This builds independence and strengthens your awareness of the scale's symmetry. Aim for a crystalline quality in your phrasing to match the natural character of this scale.
