The music speed is usually marked with words or numbers at the beginning of a piece of music. Modern custom is to use beats per minute (beats per minute). minute (BPM for short) as a unit. This represents the number of times a specified note, such as a quarter note, occurs in one minute. For example, in the picture above (=120), 120 is its BPM value, which means playing 120 quarter notes per minute, that is, the length of each quarter note is equal to 1 minute divided by 120 equal parts = 0.5 seconds (as in the picture above, the time signature is 4 /4 beats, one measure is 0.5 seconds times 4 beats = 2 seconds long). The larger the BPM value, the faster the speed.
