Hey guys,
I'm from Slovakia and I learn music theory in school, so I don't know all of the english words of it, so sorry about that. Anyway, in many tutorials people tune different oscillators apart, like OSC1 is +0 semitones and OSC2 is +5 semitones. But how can this work? I'll give you an example, let's say we're in C Major and the synth that has the oscillators tuned differently is playing the note C (greyed out notes are not in key/scale) :
B
A#
A
G#
G
F#
F-OSC2 (5 semitones up; perfect fourth, correct?)
E
D#
D
C#
C-OSC1
But what if I want to make a perfect fourth from F?
B
A#-OSC2 (5 semitones up; perfect fourth, correct?)
A
G#
G
F#
F-OSC1
E
D#
D
C#
C
And A# is out of the C Major key/scale.
Even perfect fifths don't alway work, look, we'll be in G Major now (has F#) and the note played is F#:
D
C#-OSC2 (7 semitones up; perfect fifth, correct?)
C2
B
A#
A
G#
G
F#-OSC1
F
E
D#
D
C#
C1
I'm not even too good at music theory, but I just can't understand this. Help?
And BTW: what's the difference between Key and Scale?
