The number of bars used when sequencing drum samples can vary quite a lot. Usually, the total number of bars will be equal to the length of the song as a whole, and if you’re making loops to start with, it can be a bit more complicated.
If you’re composing a standard loop and want to portray a general outline of your song in a fairly straightforward manner, using four bars should be enough. The theme of the song can be condensed into these four musical bars, and the sample should be able to stand on its own; that is, you should not need surrounding music to really give the sample context. You should also add some variance in the drum samples or instruments, and a popular method is to do this toward the end of the forth bar. Keeping the listener comfortable and yet not sure what comes next is the aim of the game here, so remember that variance is key, even in a measly 4-bar loop.
Sixteen bars is another common loop number, usually because in hip hop, 16 bars is a typical vocal verse length. So if you can develop the 16 bar loop, complete with pre-chorus introduction and an 8 bar switch-up (just an example), you can give a good example of the way the song would be structured. Using drum samples over these 16 bars will give see you test your creative limits, especially if you make a few beats every day. Introducing the hi-hats starting at bar 8, for instance, gives the song a great motion factor.
Looking beyond drum samples can expand your horizon a little bit and it actually opens a whole bunch of doors. One common switch-up in a 16 bar loop, for example, is the introduction of a new instrument after 8 bars instead of anything drum-related. However, at this point – or anywhere else in the loop – you could mix up the drums to coincide with this change, and this can be very powerful.
Looking outside instruments and drum samples, vocals can also be a great trigger tool. A singer or rapper may perform the first four bars in a very monotonous tone and then simply explode with emotion. This is a wake-up call on its own, but coupled with the other techniques, you could really run wild in your listener’s mind.
With all of this on the table, you may be asking, “so what’s the easiest way to switch up the music?” The answer is indeed drum samples. It’s so easy to change the sequencing here, and your singer does not need to do anything different, and your keyboard player doesn’t need to come in again to lay down new harmonies for the song. It’s that easy.
