Erquan Position Study Jianpu (Numbered) Notation

Tune both strings before the first stroke — everything in Erquan Position Study sits in first position on the inner D and outer A string, so the two open pitches carry the whole piece. The numbers are jianpu: 1 is the home note, dots mark the octave, and a line under a digit halves it. Play one full bow per note at first, slow and even, and let the app's pitch feedback tell you where a finger sits sharp or flat — with no fingerboard and no frets, the sound is the only witness.

Where 滑 marks a huayin slide, start the note low and glide up smoothly into pitch — the app grades the slide's start, end and whether it moved in one direction. Keep the metronome well under around 58 BPM, keep bow changes quiet, and loop the phrase that grades worst until the left hand stops guessing. By the numbers, this setting runs 13 notes across 4 bars, from D4 up to D5 in 4/4 time.
