Unique wood pattern made from solid beech wood and integrated Bluetooth speaker. Hand gestures to control the figure allow for play or pause, volume adjustment, or turning 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 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 can be adjusted for solo performances, while it is fixed in the choir. The pitch ranges 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.
