Why am I practising this?expand
What it teaches
Chord tones as physical shapes, in every inversion, so that harmony is available from any starting note rather than only from the root.
Problem it solves
Root-position-only arpeggios make lines predictable and force awkward leaps when the harmony moves.
Physical skill
Inversions place the same chord in different parts of the horn, evening out your control across registers.
Theory reinforced
Dominant seventh: 1 3 5 b7. Function: Dominant.
Improvisation
Starting an idea from the 3rd, 5th or 7th instead of the root is the fastest way to stop sounding like an exercise.
Ear training
Sing the 3rd and 7th before playing — those two notes carry the chord's identity.
Common mistakes
Always starting on the root; letting the top note of the arpeggio go sharp; ignoring the descending form.
Recommended tempo
60-80 BPM in eighth notes, ascending and descending, no gap between keys.
Increasing difficulty
Two octaves, then alternate inversions between keys, then move through major thirds instead of fourths.
Mastered when
Any inversion of the chord, from any of the twelve roots, at tempo, without hesitation.
How to practise it
  1. 01Play the chord type in root position around the whole cycle.
  2. 02Repeat starting from the 3rd, then the 5th, then the 7th.
  3. 03Alternate ascending and descending between keys.
  4. 04Finish by playing only the 3rd and 7th of each chord around the cycle.
