What is the term used for holding onto the combined value of tied musical notes?

The term for holding onto the combined value of tied musical notes is referred to as "hold." When musical notes are tied, it means that the second note is held for the combined duration of both notes. The concept of tying notes is crucial in musical notation as it extends the length of a single pitch, allowing for a smoother melodic line without the interruption of a new note. The practice emphasizes the sustained sound, and thus, the term “hold” appropriately denotes the action of continuing the sound.

In contrast, "rest" refers to a period of silence in music, which is not what's happening when notes are tied. "Beat" relates to the rhythmic pulse of music, indicating the timing, but doesn't concern the specific action of sustaining tied notes. "Pause" can suggest a brief stop or silence in music, which again does not relate to the value of holding tied notes. Therefore, the choice of "hold" correctly captures the concept of sustaining the duration of notes that are tied together.
