# Tutorial 2: Algorithmic Manipulation

The code below plays the first four notes of the default scale on repeat:

``` python
p1 >> pads([0,1,2,3])
```

It's possible to manipulate this by adding an array of numbers to the Player object
This raises the 4th note played by 2 degrees

``` python
p1 >> pads([0,1,2,3]) + [0,0,0,2]
```

And this raises every third note by 2

``` python
p1 >> pads([0,1,2,3]) + [0,0,2]
```

These values can be laced and grouped together

``` python
p1 >> pads([0,1,2,3]) + [0,1,[0,(0,2)]]
```

This behaviour is particularly useful when using the follow method.

``` python
b1 >> bass([0,4,5,3], dur=2)
p1 >> pads().follow(b1) + [2,4,7]
```

You can schedule players to do things
This will tell p1 to reverse the notes every 4 beats

``` python
p1 >> pads([0,2,4,6])
p1.every(4, "reverse")
```

You can "chain" methods together by appending them to the end of
the original line:

``` python
p1 >> pads([0,2,4,6]).every(4, "reverse")
```

To stop calling "reverse", use `never`:

``` python
p1.never("reverse")
```

Here are a few other methods you can use:

Using `stutter` will play the same note `n` number of times with different attributes specified

``` python
p1.every(4, "stutter", 4, oct=4, pan=[-1,1])
```

Rotate will move all the values over by 1 in their order

``` python
p1.every(4, "rotate")
```

To randomise the order of the notes, use `shuffle`

``` python
p1.every(4, "shuffle")
```
