##| Recreating a Colin Bender arppegio pattern from lockdown day 40
##| Cm, Abmaj, Ebmaj, Bdim
##| intervals for readability
root = 0
second = 1
third = 2
fourth = 3
fifth = 4
eighth = 7
tenth = 9
##| the 4 arpeggios
cm = scale(:c5, :minor, num_octaves: 2)
abM = scale(:ab4, :major, num_octaves: 2)
ebM = scale(:eb5, :major, num_octaves: 2)
bdim = chord(:b4, 'm+5', num_octaves: 2).reverse.drop(1).reverse
##| interval pattern for the first 3 arps
indices = [root, third, fifth, third, eighth, fifth, tenth, eighth]
##| the bdim has a slightly different interval pattern
dim_indices = [root, second, third, second, fourth, third, fifth, fourth]
##| setup the scales and intervals list to iterate
scales = [cm, abM, ebM, bdim]
intervals = [indices, indices, indices, dim_indices]
##| constant for the time (0.1 ish is nice but can be too fast for some PCs so change as needed)
note_duration = 0.105
##| loop through the arps!
