Like chords but can’t be bothered learning them? Try the following python program:
"""
Generates chords from a single root note.
Route your keyboard through CHORDS.
The chord formulas are consecutive half-steps from
the root note.
"""
from mididings import *
# print flag (set to 1 to print midi notes)
pf = 0
# Chord formulas
chords = (
{
"Chord" : "Major",
"Formula" : [4,3]
},
{
"Chord" : "Minor",
"Formula" : [3,4]
},
{
"Chord" : "Power",
"Formula" : [7]
},
{
"Chord" : "add9",
"Formula" : [4,3,7]
},
{
"Chord" : "maj7",
"Formula" : [4,3,4]
},
{
"Chord" : "maj9 (ext)",
"Formula" : [4,3,4,3]
},
)
def Chord(n):
f = chords[n]["Formula"]
r = Pass()
tt = 0
for t in f:
tt = tt + t
r = r // Transpose(tt)
