This is also known as an anacrusis. Rubato is when the performer is given the freedom to relax the tempo and hold it back. What is an anacrusis? An upbeat. Rhythmic devices Syncopation is when notes are held over beats, not only offbeats.
Cross rhythm is the effect produced when two conflicting rhythms are heard together. Pay particular attention to the snare drum, which suddenly drops to half speed.
A double-time tempo change should be fairly easy to perform, since all you need to do is subdivide the beat into eighth notes essentially, think about eighth notes in your head and then make those eighth notes the beat when the time comes. Subdividing is a great skill to work on when preparing to record. Recording pop music frequently requires playing along with a metronome, and you might find that subdividing helps you match the metronome more precisely.
Subdivision can help you change tempos as well. The problem is, how much faster? And if you have bandmates, how should you convey that information to them? Well, one possibility is to use different subdivisions of the beat to determine the new tempo. Turn on a metronome and feel the beat in groups of three. Now think of four evenly spaced notes over every three beats, creating the four-against-three polyrhythm we discussed earlier in this chapter.
Now, as a final step, remove the underlying quarter note and treat the rhythm in the upper voice as the beat. We can also do this with other divisions of the beat. For example, in a song with a triplet feel that is, in a song in which at least some of the beats are divided into three parts, rather than two or four , we can use subdivisions of triplets to transition to a faster tempo. For a more thorough explanation, see Appendix B.
The subdivisions of those notes allow us to properly place the triplet quarter notes in the second measure, because the triplet eighths are easier to perform precisely and are half the value of the triplet quarters.
In the third measure, our triplet quarter notes will become regular quarter notes, resulting in a faster tempo. We can also use this sort of device to transition to a slower tempo.
We begin with quarter notes and then subdivide into eighth notes. In the third measure, the dotted quarter note of the old tempo becomes the quarter note. A dotted quarter is the same duration as three eighth notes. Therefore, the eighth notes in the second measure will be the same duration as the triplet eighth notes in the third.
As a result, our tempo will drop from beats per minute to This emphasizes the weak part of the 2nd beat. This example is more syncopated; all weak beats are emphasized, resulting in more tension. The rhythm in question may simply not communicate a meter, in which case the musicians rely on the listener to be able to predict the metrical framework.
Cross-rhythm is an example of this. Cross-rhythm occurs when a rhythmic pattern suggests more than one meter.
An example is 3 against 4 — three equally spaced beats played against four equally spaced beats. Depending on how you listen, it can be one or the other. The ambiguity created by this phenomenon can create a lot of tension; and adding more layers with different meters adds more tension.
Metric displacement occurs when a rhythmic motif starts in a particular location….
