METHOD AND DEVICE FOR FORMING MUSICAL SOUND

PROBLEM TO BE SOLVED: To make possible evading an unpleasant feeling due to a repeat when an intentionally edited and recorded musical sound as background music is played by forming the musical sound reflecting a condition of a wind at the moment based on the wind data such as wind speed, etc., in a measurement place and outputting it as a musical composition. SOLUTION: A sample-hold circuit 2 samples the wind speed data of an anemometer 1, and holds temporarily them in a buffer memory 3, and holds the next data by arrival of the next data. A pitch data forming circuit 4 reads out the pitch data answering to the wind speed data stored in the buffer memory 3 from a pitch data table 5. Further, a note length forming circuit 14 reads out the note length data answering to a mean wind speed change rate temporarily stored in the buffer memory 13 from a data table 15. Then, a musical sound forming circuit 6 receives respective data from the pitch data forming circuit 4 and the note length forming circuit 14, and synthesizes them, and forms the musical sound data to supply them to a musical sound adjustment circuit 17.
