Crotales

Crotales, also known as antique cymbals, are percussion idiophones made from small tuned bronze or brass discs (cymbals). They have a diameter of around ten centimetres with a flat surface and a bulge at the bottom. They can be played with sticks or mallets. However, you can also strike two crotales against each other as with the tingsha or use a bow. The sound is similar to that of a bell, but is brighter and resonates longer.
Today, crotales are arranged chromatically over up to two octaves, but usually one octave. Together with the glockenspiel and the celesta, crotales are among the highest percussive orchestral instruments. They are transposing instruments and are usually notated over two octaves lower than the actual sounding note in order to avoid many auxiliary lines.
