Learn erhu through a graded course in jianpu, with feedback that tells you how far and which direction to move. Soloist Erhu pairs an instrument-specific tuner with a structured path from first bow to graded repertoire. HONEST DIRECTIONAL INTONATION A fretless instrument should not answer every miss with a red light. Soloist Erhu shows whether a note is flat or sharp, reports the distance in musical cents, and tells you to move toward or away from the qianjin. Optional digital string marks give new players a visual landing point. If the microphone signal is unclear, the app asks for another take instead of inventing a wrong-note verdict. A REAL JIANPU COURSE Follow 98 structured lessons in numbered notation. Catalog v7 contains 3 source-verified public-domain arrangements, 95 original erhu studies, and 392 accompaniment-only play-along charts. The course develops inner- and outer-string control, bow changes, rhythm, shifting, and musical phrasing in a deliberate sequence. HUAYIN AND ROUXIAN FEEDBACK Slides are checked for their start, destination, and contour. Vibrato practice measures rate and depth against clear target bands. Technique feedback is confidence-gated so an uncertain recording never becomes a confident judgment. A TUNER BUILT FOR ERHU • Inner D and outer A auto-detection • Six xianfa key systems: D, G, F, C, A, and B-flat • A4 calibration from 428 to 452 Hz • Reference-tone listening mode • Directional cents display and microphone-noise guidance POSITIONS THAT BECOME MUSIC Learn positions 1-3 through graded landing and shifting drills, not a static finger chart. Jianpu string roles connect directly to the course so key changes make musical sense. FREE AND PRO The erhu tuner remains available without Pro. Soloist Erhu Pro unlocks the complete course, advanced intonation coaching, position work, and slide and vibrato analysis. Monthly and yearly plans are shown from the App Store before purchase; any introductory offer appears only when the App Store says the account is eligible. Subscriptions renew automatically unless cancelled in Apple Account settings. Restore Purchases is always available. The course is taught in English and uses hanzi, pinyin, and plain-English technique names where they help.
