An electronic trumpet emulating the valves of a trumpet, playable without a mouthpiece. Electronic sensors detect valve positions and pushbuttons select note intervals and play notes when pressed. An internal microcontroller translates valve and button states into Musical Instrument Digital Instrument (MIDI) messages suitable for transmission to an external music synthesizer or internal MIDI Synthesizer Integrated Circuit.

An information processing apparatus includes: a storage storing a program; and a processor that performs control in accordance with the program, wherein a sound production timing is a timing of producing a sound of a note, the sound production timing being specified in a musical piece; and an early press period is between an early time point and the sound production timing, the early time point being earlier than the sound production timing by a predetermined time. In a situation that a performance action is detected within the early press period, the processor causes a sound production unit to produce a sound corresponding to the performance action at the sound production timing. In a situation that no performance action is detected within the early press period or at the sound production timing, the processor does not cause the sound production unit to produce a sound at the sound production timing.
