There’s lots of uses for these kinds of thing.Ĭontrary and parallel octaves. So you’ve already played the G in the left hand and then you come in on the F in your left hand on beat 1. If that’s not appropriate, in other words if you’re on the G 7th chord you may want to play G in your left hand the beat before that and then get together on the next beat. If you’re going to the C chord you can go up from G and down from F. Contrary motion is nice too because it moves in opposite directions, for example. We just talked about parallel motion so far.
Get the idea then use both hands and spread it out to octaves. You can do it in thirds first just to get the feel. So experiment with those parallelisms in octaves if you would. Now you could do the same thing if you’re going up to say E flat. You see you’re landing on the 7th chord or the A chord. For example my left hand’s playing C, B, B flat, A and my right hand a tenth above that E, E flat, D, C sharp. But if you go down a third or even if you go up a third for that matter you’ve got to do it chromatically. Another thing you can do is if you’re going down a third you can do it in triplets or take all three beats if you’re in 3/4 time. There’s a lots of rhythmic varieties to that obviously. Of course there’s many varieties to that. My left hand’s going down from C down to G. You can also do it : you probably wonder if I can go down. Triplet and then I’m there because I’m breaking the unit of time down into three segments. In other words if I went one, two, triple it, I could do it all on the third beat there couldn’t I? Or all on the fourth beat if I played it in triplets. If I was in 4/4 time then I’d have to start on B too wouldn’t I? One, two, three, four one : so it’s just a matter of timing because you obviously can’t get to where you’re going until it’s time to get there, so you want to delay that.Īnother thing you can do is do it in triplets. For example if I’m moving from C to F I can simply walk up in tenths or thirds. Now when can you use these parallel octaves? Whenever the chord moves up a fourth you can do it. My thumbs are only a third part and yet the rest of it, like it’s a tenth from my little finger to my right hand thumb and it’s an octave and a half from my little finger to my little finger. You could say it in thirds if you play your hands close enough together because my thumbs.
If I play the C in octaves and the E in octaves that’s a parallel octaves in tenths. But if I take that E and move it up an octave that’s called a parallel tenth. In other words if I play C and E together that’s a parallel third. What’s going on is that the left hand is playing an octave and the right hand is playing an octave and they’re going in the same direction. Those are parallel octaves that you’re hearing there. Sometimes you’ve probably heard me in my teaching do things like this. Today I’d like to talk a little bit about parallel & contrary octaves in piano playing. This is Duane with some more good stuff you really ought to know. Here is a transcript of the podcast if you would like to follow along:ĭuane: Hello again.
#Octave parallel how to#
This widespread in-field validation allowed showing good performances not only in speedup but also in efficiency using Dragonfly.Parallel & Contrary Octaves in Piano Playing – How To Use Them Finally, this tool has been tested on different computer systems from standard commodity environments to medium size clusters using a set of applications from different scientific fields. These functionalities allow obtaining good performance metrics such as: execution time, scalability and efficiency. To distribute the workload, it has a flexible system, where programmers can select the computational resources, create clusters and assign weights to balance properly tasks across the distributed environment (MATLAB and Octave instances machines) with different computational power. Dragonfly can be used under multi-platform (Linux, Windows, Mac) and multi-environment configurations (e.g., MATLAB and/or Octave instances).
#Octave parallel software#
In this paper, we present Dragonfly, a free open-source software toolkit that allows creating a parallel collaboration environment between MATLAB and/or Octave instances, allowing us to have a robust system, which is flexible, transparent and interoperable.
