Explore chords and scales
Search, hear, and compare chord and scale structures. Explore alternative symbols, omitted notes, voicings, arpeggios, and melodic patterns to understand how each interval changes the musical colour.
Quick guide
- Search for a chord or scale, or use the available filters.
- Open an item to explore its notes, intervals, symbols, and variants.
- Use Play to hear all notes together, or Arpeggio to hear them separately.
- Choose a Voicing preset to change the spacing and register of the notes.
- Open Run to practise the notes with ascending, descending, intervallic, or Bergonzi patterns.
- Compare complete chords with no-root, no-third, no-fifth, or no-seventh variants.

Learning tips
Build your harmonic ear
Listen before you analyse
Play an example once without looking at its formula. Then listen again while identifying the root, third, fifth, extensions, and altered notes.
Compare small changes
Choose related structures such as C7, C7(no5), C7♯5, and C7♯11. Notice how changing or removing a single degree transforms the chord while part of its identity remains.
Practise effectively
- Study one chord or scale family at a time.
- Compare several examples with the same root.
- Alternate between block playback and arpeggio playback.
- Try the same structure with several voicing presets.
- Use scale runners to turn theoretical notes into playable melodic material.
- Repeat the exercise in several keys.
Try this exercise
Start with C7. Compare the complete chord with C7(no1), C7(no3), C7(no5), and C7(no7). Identify which omitted note changes the chord’s identity most strongly, then repeat the comparison with a different root.
