Now I'm gonna have a go at creating some contrasting ostinati for my first section. The first thing I need to do is to choose my instruments. So I'm gonna create a new track, and I'm gonna choose a contrasting instrument that I think sounds different, but also blends well with the instrument that I already have, which is marimba. There's lots of things you could choose from. There's no right or wrong as such, you just want something that fits well with what you got, but is definitely contrasting and slightly different. The one I'm gonna choose to use for the purposes of my first ostinato is classical acoustic guitar. It sounds quite different to the marimba, but I think they go quite well together as well. (gentle rhythmic music) So that's what I'm gonna choose to use. Now, when we're creating contrasting ostinati, there's a couple of ways we can help them contrast. And the first is by using contrasting rhythms. So the rhythm of my marimba ostinato is this. (gentle rhythmic music) It's just crotchets on each beat. So what I'm gonna try and do is I'm gonna do some improvising. I'm gonna put the looper on, and it's just gonna keep playing over. And I'm gonna try and create an ostinato using some of the notes of that D minor pentatonic scale that uses a different rhythm to the marimba rhythm. So maybe notes that aren't on the beat, or maybe some faster rhythms, and I'll see what I can come up with. Here we go. (bright rhythmic music) (bright rhythmic music continues) So there was lots of different patterns there that I came up with, and all of them, I'm still using those notes of that scale, but trying to use different rhythms, maybe some faster rhythms, some rhythms that were off the beat. The one I think I'll use is gonna be this one. (bright rhythmic music) I think that works quite well. So I'm gonna record that in now. (recorder beeping) (bright rhythmic music) And you'll notice it's four beats long, it's one bar long, and for now I'm just gonna loop it to bar 16 as well. Now I'm gonna create another one. Again, a contrasting instrument. I think for this one, we'll maybe go for, let's try some orchestral instruments. Maybe let's do some orchestral strings I could use. Now, so far I've used lots of short notes, but what I don't have is any sustained notes, notes that are held and last for a long time. So I think with this one I'm gonna experiment and try and create an ostinato that uses some sustained notes, some long notes. So let's see what I come up with. (bright rhythmic music) (bright rhythmic music continues) I think I've found one which I like, so I'm gonna record it in. (recorder beeping) (bright rhythmic music) So it only uses two notes, but the first one is quite long and sustained, which means that it creates quite a lot of contrast with the other tracks that I've already created. Let's loop it to bar 16.
