Musical markings are symbols used by composers and musicians to indicate how a piece of music should be performed. NOTES are the written representation of a musical sound, and they can be written in various forms such as whole NOTES, half NOTES, quarter NOTES, and eighth NOTES. Tempi are the speed at which a piece of music should be played, and they can range from very slow to very fast. Both NOTES and tempi are essential components of musical markings, and they are used to ensure that a piece of music is performed correctly.
