Duplicate strings
Off — some notes have a second string elsewhere on the photo that repeats the same pitch. Tap to reveal and play those too.
Note legend
Off — in landscape/fullscreen play, types notes live down the right edge of the screen (past the last string, where there’s nothing to cover) as you strike them, with the current one highlighted. Handy for recording your screen so viewers can see which string is which note.
Note log
Off — tap “Start logging notes” only when you want to capture what you play, then Save when you're done.
About
Virtual Yangchen + Tuner
This app turns your phone into two instruments in one: a precise tuner for a real yangchen, and a playable virtual one you can practice on any time.
The yangchen is a traditional Bhutanese hammered dulcimer — also called the dratong for its many strings. A real one is a serious investment, so this app closes that gap: strike any string on the screen to hear it and start learning the instrument before you ever own one, then use the built-in tuner to keep whichever physical yangchen you do have in tune. No quiet room or spare afternoon with the instrument required — it travels in your pocket, ready whenever the mood strikes and wherever you are.
Beyond that, the app carries a simple mission: to help keep Bhutan’s traditional music alive and within reach, for anyone curious enough to pluck a string.
This locks the app again on this device. Enter the same activation key again any time to unlock it — no need to contact the seller unless you've lost it. Continue?
