# Performance

This page will present you all the functions that will be useful during the performance: tempo management, reset, etc... Each function will be presented following the same model:

**Type signature**: how the function is declared on the**Haskell**side.**Description**: verbal description of the function.**Examples**: a small list of examples that you can copy/paste in your editor.

Tempo### #

setcps`setcps`

is a global function that adjusts the number of cycles per second. This function can accept integers, decimals, and fractions.

The default number of cycles per second is `0.5625`

, which is equivalent to `135/60/4`

.

These two values are equivalent:

**Cycles per second**: as a decimal,`setcps 0.5625`

.**Cycles per second**: as a fraction,`setcps (135/60/4)`

Representing cycles per second using fractions has the advantage of being more human-readable and more closely aligned with how tempo is commonly represented in music as beats per minute (or bpm). Techno has a range of `120-140 bpm`

. House has a range of `115-130 bpm`

. And so on. If we wanted to set the tempo of our Tidal song to fast house, we would do the following:

Regarding the example above, the first part of the fraction `(130/60)`

says there will be `130`

beats per minute. `130`

is the number of beats and `60`

is the length of the minute (`60`

seconds). The second part of the fraction (`/4`

) says that for every cycle in tidal there will be `4`

beats. You can adjust this value to change how quickly your cycles run.
