 Of course, we can change the 10 to whatever number we want. Go on, try
 it! What if we want to loop forever? We simply say loop instead of
 10.times. Also, I'm sure you're asking what the magic 1.753 represents
 and how I got it. Well, it's the length of the sample in seconds and I
 got it because I asked Sonic Pi:

 And it told me 1.753310657596372 - I just shortended it to 1.753 to make
 it easier for you to type in. Now, the cool thing is, we can combine
 this code and add a variable for fun:
