Organo di Legno

• Other names: Wooden Pipe Organ
• Family: Winds / Keyboard
• Description: A small chamber organ with wooden pipes which was well known in the Renaissance, but of which there appear to be no other surviving examples except for one made by Lorenzo da Pavia in Venice in 1494 that is now kept in the Museo Correr, Venice, Italy. Such instruments were prized for their sweet sound, described as "soave". Lorenzo's organ was pitched at a' = 455 Hz (± 4 Hz), one of the fairly high Venetian instrumental pitches. The compass is F,G-f³ (i.e. no F#), which retains the possibility of using the upper part of the range for repeating melodies at the octave.
