Corona is an experimental classical composition for one or multiple pianists by Japanese composer Toru Takemitsu.

In this way, traditional notation provided a way to discern and to identify compositions, as notes are merely a large set of rules by which a particular musical piece has to be performed.

[1] During this period, Takemitsu wrote four compositions with graphic scores, some of them in collaboration with Japanese artist Kōhei Sugiura.

[2] The composition was completed in February, 1962, and premiered in Tokyo that same month, with Toshi Ichiyanagi and Yuji Takahashi at the piano.

The piece has a short rhythmic and melodic motif which is stated in the first study alone, the only corona in which specific pitches are identified.

[5] The first commercial recording of Corona was released in 1973, performed by Yuji Takahashi, who had premiered the work in Tokyo in 1962.
