The term of music sounds can be summarized as tones, which is a five-letter word. Tones are the basic elements of music and refer to the sound produced by a musical instrument or voice. They are the building blocks of melody and harmony and are used to create musical phrases. Tones can be described in terms of pitch, duration, intensity, and timbre. Pitch refers to the highness or lowness of a sound, while duration is the length of time a tone is held. Intensity is the loudness of a tone, and timbre is the quality of a tone that distinguishes it from other tones.
