ることを特徴とする電子楽器。 An electronic musical instrument that detects the period of a fundamental wave from a musical tone signal and generates a new musical tone signal based on the detected period, comprising a storage means for sequentially storing the detected detection data, and arbitrarily selecting the data from the storage means. The apparatus includes a selection reading means for reading, an envelope detecting means for detecting an envelope of the musical tone signal, and a musical tone signal generating means for generating a new musical tone signal based on the read data, In connection with this, by generating a new musical tone signal based on the detection data before the detection time that is arbitrarily selected and read from the storage means, a musical tone with a stable frequency can be generated even when the cycle of the musical tone signal suddenly changes. An electronic musical instrument characterized by the fact that
