Drum and bass / gamelan Album: Golden Hour (2010) Track: Islands

Fun hip hop ish beat in 13-tone equal temperament aka 13edo which squeezes one extra note into the octave then makes all the notes equal size. One cool thing about 13-tet is, if you play a whole-tone scale, it will miss the octave completely and won't repeat until you reach 2 octaves, using up all 13 notes in the process! You can hear this about half way through the track.

A track from Golden Hour, my 2010 album. This composition was written in 22-tone equal temperament. It's a fantastic microtonal tuning which I have fallen in love with. The scale I played is a dissonant tuning, but the use of percussion instruments hides that fact, and shows a lot of tonal colour.

5/4 drum and bass / Carlos Alpha scale Album: Golden Hour (2010)

Breakbeat electronic / just intonation Album: Golden Hour (2010)

Microtonal music from 'Golden Hour' - some straight-ahead drum and bass in the equal pentatonic mode of 15-tet. It's a very fun microtonal scale to play. There's a passage of diatonic 15-tet and one glissando, but there are many things yet to explore in this musical tuning.

Dubstep wubs in the Bohlen-Pierce scale. An alien tuning for an alien genre. Experimental microtonal music from my 2010 album "Golden Hour".

Smooth and melodic drum n bass using just intonation tuning. I have no idea what the intervals are... this time I used a "JI-11" preset which was on my synth.

Short and sweet microtonal music in the Bohlen-Pierce scale - this funky drummer sampling microtonal track was fun to write. The weird mood of this song is due to the Bohlen-Pierce scale which divides the perfect twelfth into 13 equal parts. It's a scale that doesn't contain octaves. That's an alien concept for most music, but it's ripe for musical exploration.

Drum'n'bass / rock tune performed in a scale that I accidentally discovered. Actually the scale doesn't have much use, it is way more out-of-tune than 12-tet - but it was a fun challenge to try to make listenable music out of it. I'm happy with the result, so bad news for just intonation fans! Looks like musicians don't really need perfect tuning after all.

Microtonal melodies and time signature changes are all good fun. This track is from my 2010 album Golden Hour.

Atmospheric drum and bass / 22 tone equal temperament Album: Golden Hour (2010) I heard this 8 note subset of 22edo used by City of the Asleep and made Ganymede in the same scale. The scale degrees are: (1) 3 5 7 10 12 14 16 18 20 (1).

Microtonal hip hop instrumental in Wendy Carlos' Beta tuning. This tuning divides the just perfect fifth into 11 equal parts. This gives 18.809 pitches per octave. It's a non-octave scale and also a stretched variant of 19-tone equal temperament.

All praise the amen break, sliced once again for this drum and bass track. I used a just intonation microtonal scale that is based on the intervals 7/4 and 7/6, and combinations of these. We are in xenharmonic territory here, as most Western music doesn't make use of these septimal intervals. Drum and bass mixed with trance with some experimental weirdness thrown in for good measure.

This is the final track from my 2010 album Golden Hour. It uses a just intonation scale I created myself. This is one of my earlier pieces of microtonal music, and it's very chill. The bass improv in the second half of the track is in Carlos Super Just scale, which is a just intonation version of 12-tet. A track for the late night imo.

Human Astronomy EP is free to download at https://sevish.bandcamp.com/album/hum... -- 5 more dance-influenced tracks with the powerful harmonies, melodies and moods of microtonality. Released via split-notes Microtonal Netlabel. "Human Astronomy" is the first track on the EP. This is perhaps more melodic and uplifting than most of my work. Wendy Carlos' Beta scale was used, which is essentially a stretched form of 19-tone equal temperament. I like Beta's heart and warmth, used here to fill up the vertical soundspace with stacked chords.
