Unique wood pattern made from solid beech wood with an integrated Bluetooth speaker. Hand gestures to control the figure allow for playing or pausing, adjusting the volume, or turning it off. "Olga," a contralto from Russia, is one of eight singing choir wood figures with different culturally related vocal ranges and sound characteristics. It can be paired with various MIDI keyboards, as well as with the "Ortho" remote control. The figure communicates with other choir figures via Bluetooth Low Energy and offers up to four hours of uninterrupted playtime. The pitch is adjustable for solo performances, while it is fixed in the choir. The pitch range is from e3 to c5 (161.82 - 523.25 Hz). It plays a pre-programmed repertoire of classical compositions based on a contrapuntal melody or can be controlled via an external MIDI keyboard.
