So, for music in 3/4 time (such as the Skater's Waltz mentioned above), the whole-rest would be only three quarter-notes long. The half-rest resembles the whole-rest, except it sits above the third staff line rather than hanging from the fourth line (staff lines are numbered starting from the bottom). Therefore, the half-rest only lasts half as long as the whole-rest.
In practice, musicians generally indicate the length of rests by writing them out as long or short notes. For example, they might write "0.5" to mean "half note". However, because there are no visual cues to help them play through the rest correctly, some musicians may leave out notes within the rest. For example, they might play only the first and fifth notes of the rest (a semibreve and a quaver), thereby implying that they should last half as long as written.
The use of the half-rest is very common in jazz where it often indicates a change of meter. For example, if the music was in 4/4 but now moves into 3/4, the half-note would be played at the beginning of this transition. Alternatively, if the music was in 3/4 but now switches to 2/4, a half-note would be played at the end of this transition.
Half-notes appear quite frequently in pop music too.
3. A quarter rest is the rest with the 1/4 beneath it. It is one beat long, or one-fourth of a conventional measure. Half notes and half pauses are usually two beats long and half the duration of a complete note. A quarter rest is used to indicate that a moment's silence should be interpreted as meaning "no" rather than indicating some other form of punctuation.
4. A quarter rest is played at the end of a sentence, clause, or phrase to indicate that there is no more to say on the topic. A speaker might use this device at the end of a presentation to suggest that the audience has heard enough for now. A listener can tell that another topic is being discussed by the tone of voice or subject matter; here, the speaker does not want to distract from that conversation by saying more. Quarter rests are also used in music to indicate the end of a section, movement, or part.
5. A quarter rest is worth 0.5 points. This makes it equivalent to a half note, which is equal to 1 point. A quarter rest can be used instead of a half note except in cases where they would have different values (for example, if the composer wanted to indicate that a half note should be played but couldn't because it would give away the ending of the song).
It's half the length of a full sentence. A half rest is located directly above the middle line on a five-line musical staff. It indicates that no note should be played in that space.
The term "half rest" can also refer to an extended rest used at the beginning of a passage or section of music. This would include any note longer than a quarter rest.
Half rests are used to indicate that certain notes should not be played. They can be used instead of marking those notes with a dot (as is done for full stops).
For example, if it was determined that G4 was to be played but not printed, then a half rest would need to be placed over the fourth line of the staff. The stem of the g string would have to be bent back toward the body to accommodate this note.
A half rest does not change the pitch of the note it marks; it only tells musicians not to play that note. If you want to indicate that G4 should be played but not printed, then a half rest would be used instead of a dot on the staff.
Half rests are used in many types of music, including opera, ballet, and jazz.
