For her 2011 album Biophilia, Icelandic artist Björk developed an instrument based on a Tesla Coil and a second instrument described as a cross between a Gamelan and a Celesta, dubbed the "Gameleste." In 2013, a research team of McGill University came up with digital musical instruments made in the form of Musical Prostheses. In 2014, Andrei Remyannikov of Russia developed the RAV vast drum.

Recorder (musical instrument) In recorders, like in all woodwind instruments, the air column inside the instrument behaves like a vibrating string, to use a musical analogy, and has multiple modes of vibration. These waves produced inside the instrument are not longitudinal waves, like those the ear perceives as sound, but rather stationary standing waves consisting of areas of high pressure and low pressure inside the tube, called nodes. The perceived pitch is the lowest, and typically loudest, mode of vibration in the air column. The other pitches are "harmonics", or "overtones". Players typically describe recorder pitches by the number of nodes in the
