You can also think of the falling half of the passage as each bar in retrograde, seems simpler. Order by newest oldest shset. The middle voice in the chords is also restricted in this way, so it will only ever play A, C or E in some octave. If you downloaded the SID file, note that there are two subtunes.

Many people who listen to Fratres find it repetitive or even boring at first. After a while, though, they start to unconsciously recognize some of the patterns in the music. In a sense, they develop an intuitive feeling for what comes next in the sequence. Then, if they are the inquisitive, puzzle-solving type of person, they will try to understand the patterns rationally as well. This gradual awakening, whether intended by the composer or not, is perhaps what fascinates me most about Fratres.
I have interpreted Fratres in the form of a dual SID tune. What is it, this one thing, and how do I find my way to it? Traces of this perfect thing appear in many guises — and everything that is unimportant falls away. Spoilers ahead. If you enjoy solving puzzles, you may wish to search for these patterns yourself. In any case, I strongly recommend you to listen to the entire piece at least once before reading on. Have you listened to it now? Structure The overall structure of Fratres is simple: Vertically, the piece is divided into two drones an A and an E that last throughout the piece , three moving voices low, middle and high and some percussion claves and bass drum.
Horizontally, ten refuges separate nine segments. Each segment contains a series of chords arranged in some kind of harmonic progression. Between each pair of segments, a recurring, harmonically empty percussion motif — the refuge — offers a moment of contemplation before the next chord sequence. The following picture illustrates the refuges and segments as a terribly long pedestrian crossing.
Each segment can be further divided into two halves: The first half consists of falling chords, and the second half consists of rising chords. Within each segment half, three voices combine to play a sequence of chords. In order to understand the algorithm behind Fratres, we just need to figure out how to form the eight chords that build up each segment half.
That is what the remainder of this article will focus on. This basically means that some voices are restricted to playing notes from a particular triad in Fratres this is the A minor triad , while other voices play melodies. The drones, A and E, are obviously only playing notes from the A minor triad. The middle voice in the chords is also restricted in this way, so it will only ever play A, C or E in some octave.
The high and low voices, however, play notes from the harmonic D minor scale. Note how the C sharp in the D minor scale contrasts with the C natural in the triad. The low and high voices Start with a harmonic D minor scale. Write it out as a circle, like this: The low voice starts at C.
The high voice starts at E and is transposed one octave further up. For the eight falling chords the chords that build up the first half of the first segment , each voice simply moves around the circle, counter-clockwise, until it completes a full revolution at the eighth chord. For the rising chords, we do the same procedure clockwise. Much like the international date line in the pacific ocean, we add a seam, where the notes get transposed one octave. This will ensure that we end up where we started.
The middle voice As mentioned, the middle voice will only play notes from the A minor triad. Furthermore, the middle voice will by definition play in between the other two voices. But these constraints alone will not be enough to guide the middle voice, so instead we devise a new circle containing the three possible notes: We want the middle voice to sync up to the low and high voices after one complete revolution.
Why four consecutive C:s? We can only speculate, but my personal theory is this: The ethereal, timeless sound of this whole piece is partly due to the fact that it lingers somewhere in between A minor and A major. This delicate balance is maintained using the C natural from the triad and the C sharp from the melodic voices. By choosing to duplicate the C in the middle voice circle, one prevents the piece from tilting too far towards A major. All right, but why not double the other C group, the one in the upper right part of the circle?
If we did that, then the middle voice would end up playing C natural at the same time as another voice would be playing C sharp. That would be too dissonant. Just like the low and high voices, the middle voice traverses the circle counter-clockwise during the first half of a segment, and clockwise during the second half. Both these journeys begin at the indicated note, e. But this circle contains fourteen notes rather than seven, so the middle voice does not play its own retrograde in the second half like the low and high voices do.
Spinning the wheels To get the low, middle and high voices for the following segments, we simply move each starting point two steps around the circle, in the counter-clockwise direction. The following diagrams show the starting points for the falling and rising halves of segment number two.
Second segment, falling half: Second segment, rising half: This rotation, two steps at a time, continues for the entire set of nine segments. Thus, segments 1 and 8 will be identical, as will segments 2 and 9.
And that is how you extract beautiful, complex harmonic content out of a simple formula.

Anonymous Mon Apr I am completely amazed by Fratres and am listening to all the versions on my online music service as the piece is new to me.
I see it is also your favorite piece. But when I looked it up on Wiki the text citing your analysis seemed a little dismissive of the piece where it says: "The chord sequences themselves follow a clear pattern, and while the progressing chords explore a rich harmonic space, they nevertheless appear to have been generated by means of a simple mathematical formula. Just wondering, your thoughts appreciated. Anonymous The word "simple" has many connotations.
By no means do I consider Fratres trivial or hollow. This makes Fratres amazing, for the same reasons that a mathematician may consider a brief, elegant formula much more beautiful than a complex formula. Simple, in the case of Fratres, means pure, elegant, perfect. Anonymous Thank you for your kind response; it helps me understand this amazing music.

I love your version above the actual concert version I found online - your version emphasizes the otherworldly chord progressions which I love the most about this piece. Especially the final part with the lowpass filter works very well. Best to all,.
