M HEART Scale Changer Harmonium

M HEART Scale Changer Harmonium — Professional Stage & Studio Grade
The M HEART Scale Changer Harmonium is a premium, professional-grade instrument engineered for classical vocalists, stage performers, and recording studios. Its standout feature — a precision sliding scale changer mechanism with 9 to 13 transposition positions — lets you instantly shift the root note (Sa) across a full pitch range without altering finger positions, making real-time key changes completely effortless.

Built for power and tonal depth, this harmonium is equipped with 3 sets of reeds (Bass, Male & Female) for a rich, layered, resonant voice. The 37-key layout spans 3 full octaves, while the left-side octave coupler doubles every note an octave lower at the press of a key — delivering extraordinary volume and presence on stage.

Crafted from heavy, seasoned tonewood (Teak/Sagwan) with a premium glossy finish, the body ensures maximum acoustic projection and long-term durability. The multi-fold bellows (7 or 9 folds) provide smooth, consistent airflow for effortless, sustained performance. A folding suitcase-style enclosure protects all mechanics from dust and travel damage, making it ideal for touring musicians.
