What are straight and swing quavers?

In music, quavers are sixteenth notes, which are notes that last for one-sixteenth of a beat. Straight quavers are quavers that are played evenly, with each quaver lasting for exactly one-sixteenth of a beat. Swing quavers, on the other hand, are quavers that are played with a slight swing or syncopation. This means that the first quaver in a group of two is played slightly longer than the second quaver, giving the music a more relaxed and laid-back feel.

Straight quavers are often used in classical music and marches, while swing quavers are often used in jazz and blues music. However, both types of quavers can be used in any genre of music, depending on the desired effect.

Here is an example of how straight quavers and swing quavers sound:

* Straight quavers:

```

| 1 e & a || 2 e & a || 3 e & a || 4 e & a |

```

* Swing quavers:

```

| 1 + ah || 2 + oh || 3 + ee || 4 + uh |

```
