The Duo is a distinctive outdoor instrument with an ergonomic curved design accessible from both sides to be enjoyed by up to four players. Tuned to the pentatonic scale, the left and right hand side are mirrored and the scale is C-major spanning 2 octaves from C4 to C6.
The notes of the Duo have no wires or strings and are individually and securely attached to the resonators for maximum vibration with incredible tones and resonance.
The Duo can be built with individual notes of aluminium, IPE or GRP. Each of these materials gives a distinct sound when played. The aluminium will produce a bright, clear tone when struck, IPE produces a strong, deep, resonant sound while GRP is fast and punchy.
The DUO CUPLA keys are made of Aluminum and GRP (Fiberglass) materials for unique outdoor music sounds at all octaves. Stainless steel legs and hardware allow this product to weather very well outside.
