The natural numbers shows more than one way to sequence electronic music with steady progressions and not only the traditional rhythmic unit of the number 8, using 4/4 time signature and progressions after 8 bars. There is an ascending range of the multiples and dividers of the natural numbers from the number 10 to the number 19 plus the prime numbers that allows to sequence steady progressive stages in music using the numbers as rhythmic units, bars or steady pulses. Liber Abaci Records have classify this natural or possible rhythmic units as the Kappa Units:
( α ) Alpha = 10 - 20 - 40 - 80
( β ) Beta = 11 - 22 - 44 - 88
( γ ) Gamma = 12 - 24 - 48 - 96
( δ ) Delta = 13 - 26 - 52 - 104
( ε ) Epsilon = 14 - 28 - 56 - 112
( ζ ) Zeta = 15 - 30 - 60 - 120
( η ) Eta = 16 - 32 - 64 - 128
( θ ) Theta = 17 - 34 - 68 - 136
( Ι ) Iota = 18 - 36 - 72 - 144
( κ ) Kappa = 19 - 38 - 76 - 152
Years ago Nathan Fake have start a different tendence using 4/4 time signature, using 12 bars to sequence steady progressive stages on the track "The Sky Was Pink" followed by the James Holden EDM remix of the same track. After it a few artists have done the same, like Jimpster on the track "Got a Hold on Your Soul" using the same pattern of the 12 bars to sequence steady progressive stages. There is another track that use a different pattern done by James Ruskin, "Marcel Dettmann - Core Box (James Ruskin Blueprint Mix)". This track is sequenced following 10 - 20 - 40 - 80 steady pulses also being obvious the melodic figure that repeats after 5 different notes.
There is a few rock bands that also have explore different rhythmic units, like Nortec in the song "Bar Inferno" using Gamma Unit in steady progessions. The Mars Volta and Tool also have experimented different rhythmic units.
Jazz music characteristic are the improvisations and experiences different rhythmic units but not sequencing on steady progressions with the same rhythmic unit as the electronic dance music does. Popular music is sequenced in multiples of 4 and only a few time signatures are known due to the rhythmic complexity of them.
The Kappa Units are all the possible or natural rhythmic units that gives the natural numbers to sequence pulses, bars and progressive stages.
