Musical instrument, method and recording medium

A method for a musical instrument that includes:

• memory that stores layout information containing a plurality of regions arranged on a predetermined virtual plane and pitch angle ranges corresponding to each of the plurality of regions;
• a pitch angle sensor that detects a pitch angle of a music playing member that can be held by a player during a music playing operation;
• and a position sensor that detects position coordinates of the music playing member on the virtual plane, the method comprising the steps of:
• determining whether the position coordinates of the music playing member belong to any of a plurality of regions arranged on the virtual plane based on the layout information stored in the memory, at a timing at which a music playing operation is made by way of the music playing member;
• determining, in a case of having determined as belonging to the region, whether the pitch angle of the music playing member detected by way of the pitch angle sensor belongs to a pitch angle range corresponding to the region;
• and
• instructing generation of a musical note corresponding to the region, in a case of having determined as belonging to the pitch angle region corresponding to the region.

A computer readable recording medium used in a musical instrument having memory that stores layout information containing a plurality of regions arranged on a predetermined virtual plane and pitch angle ranges corresponding to each of the plurality of regions;

• a pitch angle sensor that detects a pitch angle of a music playing member that can be held by a player during a music playing operation;
• and a position sensor that detects position coordinates of the music playing member on the virtual plane, the recording medium encoded with a program that enables the computer to execute:
• a first determining step of determining whether the position coordinates of the music playing member belong to any of a plurality of regions arranged on an image-capturing plane based on the layout information stored in the memory, at a timing at which a music playing operation is made by way of the music playing member;
• a second determining step of determining, in a case of having determined in the first determining step as belonging to the region, whether the pitch angle of the music playing member detected by way of the pitch angle sensor belongs to a pitch angle range corresponding to the region;
• and
• a sound-generation instruction step of instructing generation of a musical note corresponding to the region, in a case of having determined in the second determining step as belonging to the pitch angle region corresponding to the region.
