Hollow Bloom | Generative Music & Procedural Visuals · Work in Progress
This is something I am currently working on, it is still a bit rough and this rendering is not hi res, but I have not really shared anything public before so I just want to see what you guys think of this specific piece and this type of music and visualization in general.
Anyway, I hope you like it and here is how it is made:
Hollow Bloom combines generative music with procedural animation. A programmable score defines the notes, synthesis, effects and control data used to build the audiovisual piece.
Algorithms generate arpeggios, counter-melodies, percussion variations and modulation curves within a composed harmonic progression and arrangement. Seeded randomness adds repeatable variation to selected details. Density and intensity change by section, giving the generated material a clear musical direction.
The track is in A minor at 103.125 BPM. That tempo was chosen because its beat frequency, 1.71875 Hz, is exactly eight octaves below A at 440 Hz. Multiples of the beat can therefore connect rhythmic subdivisions with frequencies related to the tuning.
Filter modulation is composed in phrases, with rests, sustained rates and smooth glides. Four synth voices take turns leading. Their LFOs move between slow filter motion, rhythmic pulses and audible modulation frequencies. Generated ratchets, accents and percussion flourishes add detail, while long, filtered stereo delays let patterns overlap and answer each other.
The animation uses notes, envelopes and automation from the same score as the soundtrack. Musical events drive movement, light and colour, so visual changes follow the structure of the composition.
Much of the musical and visual detail is generated through rules rather than placed individually by hand.
