The intervals in a major scale are really the same as a minor scale. What’s different is the starting point. All the pitches in a major scale are the same as its relative minor, which is down a minor third. So the difference between a melody in a minor key and a major one is the root note. The same melody can be minor or major depending on the perspective of the listener. The last pattern I posted is only in a minor key if you consider C the root. If you consider E flat the root, then the melody is in a major key with C being its relative minor. In this case, the pattern is in C major, so if you listen with an A (the relative minor of C) in mind you’ll hear it in a minor scale.
GMS Major Scale
In my previous example of audio created with my gestural music sequencer, that I’m tentatively naming GMS, I presented a pattern of sampled Rhodes notes in a chromatic scale. One of the functions I’ve built into the application is the capability of switching scales. Currently the available scales are major, minor, pentatonic minor, and chromatic. Here’s an example of the application producing notes in a minor scale. One thing you may notice is the dynamic range. By gesturing lower within the Y axis the notes get quieter, while gesturing near the top of the screen makes notes that are louder. 
A big thanks goes out to Jason Striegel and Nick Watts for inviting us to perform at 
I’m calling this one minute and twenty four second experiment Six Machines, simply because after applying the first round of processing and looping the phrase a vague melody in six / eight time is discernible. The first round of involved applying destructive processing in 
This chord is much more similar to an example of close harmony than the open voicings that I posted earlier. Close harmony is essentially the opposite of open harmony. The notes are often clustered together and might include minor seconds. This example could be written, once again, as a poly chord or by referencing the notes used. I tend to think of it as a poly chord because In the left hand I’m playing an incomplete B flat major seventh made up of B flat, F and A, followed by a C major triad in the right, starting with the G below the A in the left hand. This means my thumbs are crossed leaving me in a good position to play arpeggios around the C triad.
