Octave Scales

Octave is a focused scales-and-modes trainer for musicians, students, and producers who want to internalize the building blocks of music — one octave at a time.

Pick a key, pick a mode, set a tempo, and Octave plays the scale back to you with a clean synthesized piano sound while a virtual keyboard lights up each note. Loop it, change direction, or stretch it across multiple octaves until the shape lives in your fingers.

KEY FEATURES
• All 12 keys (C through B, sharps and flats) on a single screen
• All 7 diatonic modes: Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, Locrian
• Built-in metronome from 40 to 200 BPM with a single drag of the dial
• Live keyboard view that highlights every active degree as it plays
• 1, 2 or 3 octave practice range
• Up, Down, or Up-Down direction with optional loop
• Browseable Library: tap any key × mode combo to see the notes and intervals
• Interval map (W/H steps) so you can see and hear the formula
• Sample-accurate timing — the click and the note land together

WHO IT IS FOR
• Piano students drilling major and minor scales for exams
• Guitarists trying to finally hear the difference between Dorian and Aeolian
