Electronic musical instrument having resonance tone generation

摘要

An electronic musical instrument including a keyboard, a CPU and a sound source. The keyboard designates a pitch of a musical tone. The CPU detects common pitch data of one of predetermined series of pitch data or interval between predetermined two pitches, when a plurality of pitches are designated by the keyboard. The predetermined series of pitch data are stored in a memory in units of pitches which can be designated by the keyboard. The sound source outputs a musical tone signal having a pitch designated by the keyboard and musical tone signals having pitches indicated by the common pitch data detected by the CPU or having pitches corresponding to the interval detected by the CPU.
