What Do The Hand Numbers Mean?
BEGINNER ACADEMY · 5 MIN READ
The numbers floating near your left hand are scale degrees. One finger is the root of the key, five fingers is the fifth — the most stable cadence in Western music, mapped to the most natural counting gesture you already know.
Thinking in degrees instead of chord names is what makes WeldSynth key-agnostic. Learn the shape once, and switching from C to Eb is a settings change, not a new skill.
Your right hand never picks chords. It shapes what the chord feels like: height is volume, tilt is the filter sweep, finger count picks the chord quality.
The mapping
Count fingers on your left hand
One finger plays degree I (the root), two fingers degree II, up to five fingers for degree V.
Tilt for major or minor
Tilt your left hand inward for a minor quality, outward for major. A small dead-zone keeps you stable.
Read the HUD
The DEGREE readout shows the Roman numeral, the CHORD readout shows the resulting chord name.
Change the key
Open settings and pick any of the 12 keys. The degree mapping stays identical in every key.
Read less, play more. Open the practice panel and try the gesture from this lesson — camera optional, Mouse Mode included.
