Furthermore, song titles, chord names, selection method icons, and lyrics are displayed and presented to the performer as musical scores.

　Fig. 5 is a flowchart for explaining the configuration of the main processing that realizes the automatic sound reproduction function.

After first executing initialization processing (step S501), the CPU unit 10 repeatedly executes a series of processing from steps S502 to S505.

The CPU unit 10 determines whether or not any piece of music to be played has been selected (step S502). If the determination is YES, the CPU unit 10 executes music data read processing (step S503). Here, data such as the title of the song, the lyrics, the number of sections, etc. are read. When the process of step S503 is completed, the process proceeds to step S504, and information based on the read music data is displayed on the screen. Next, in step S505, performance processing including an automatic sound reproduction function is executed. Details of the performance processing will be described later with reference to FIG. If the determination in step S502 is NO, the CPU section 10 skips the processing of steps S503 to S505.

Next, the CPU section 10 executes performance processing including an automatic sound reproduction function in the performance processing. Details of this process will be described later with reference to FIG.

The main processing of steps S601 to S612 is repeatedly executed, and when some operation is performed on the terminal device 1, processing according to that operation is performed.

The CPU unit 10 executes section data reading processing (step S601). Here, data such as chord information, first sound and second sound are read.

The CPU unit 10 turns off the first sound flag (step S602).

Next, the CPU unit 10 determines whether the first sound is included in the interval data read in step S601 (step S603). If the determination is YES, the CPU unit 10 turns ON the first sound flag (step S604). If the determination in step S603 is NO, the CPU unit 10 skips the process of step S604.

The processing from step S605 to step S612 is repeatedly executed, and processing is performed while the section data read in step 601 is played.

The CPU unit 10 determines whether or not a performance end operation has been performed (step S605). If the determination is YES, the CPU section 10 terminates the performance processing of step S505 illustrated in the flowchart of FIG. If the determination in step S605 is NO, the CPU section 10 skips ending the performance process.

The CPU unit 10 determines whether or not a selection operation has been detected (step S606). If the determination is YES, the CPU unit 10 acquires chord information associated in advance from a combination of presence/absence of touch operations on the manipulators of the first manipulator group (step S607). If the determination in step S606 is NO, the CPU unit 10 skips the processing of steps S607 through S611.

The CPU unit 10 determines whether or not the first sound flag is ON (step S608). If the determination is YES, the CPU unit 10 determines whether or not the chord information of the section data matches the chord information selected by the chord selection operation (step S609). If the determination is YES, the CPU section 10 starts reproducing the first sound (step S610). Next, the CPU unit 10 turns off the first sound flag (step S611). If the determination in step S609 is NO, the CPU section 10 skips the processing of steps S610 through S611. If the determination in step S608 is NO, the CPU section 10 skips the processing of steps S609 through S611.

The CPU unit 10 determines whether or not a sounding operation has been detected (step S612). If the determination is YES, the CPU unit 10 pronounces the selected chord (step S613). Next, the CPU unit 10 determines whether or not the chords match (step S614). If the determination is YES, the CPU unit 10 determines whether or not there is a sound currently being reproduced (step S615). If the determination is YES, the CPU unit 10 silences the sound (step S616). If the determination in step S615 is NO, the CPU unit 10 skips the process of step S616. Next, the CPU unit 10 starts playing the second sound (step S617). If the determination in step S614 is NO, the CPU section 10 skips the processing of steps S615 to S617. If the determination in step S612 is NO, the CPU unit 10 skips the processes of steps S613 and S614.
