# 3. Mapping lists to rhythms¶

```>>> import abjad
```

Let’s say you have a list of numbers that you want to convert into rhythmic notation. This is very easy to do. There are a number of related topics that are presented separately as other tutorials.

## 3.1. Simple example¶

First create a list of integer representing numerators. Then turn that list into a list of Durations instances:

```>>> integers = [4, 2, 2, 4, 3, 1, 5]
>>> denominator = 8
>>> durations = [abjad.Duration(i, denominator) for i in integers]
```

Now we notate them using a single pitch with `abjad.NoteMaker`:

```>>> maker = abjad.NoteMaker()
>>> notes = maker(["c'"], durations)
>>> staff = abjad.Staff(notes)
>>> show(staff)
```

There we have it. Durations notated based on a simple list of numbers. Read the tutorials on splitting rhythms based on beats or bars in order to notate more complex duration patterns. Also, consider how changing the denominator in the Fraction above would change the series of durations.
