Hey guys, i have a composition question cuz im kinda noobish in music theory and composition.
We all know that a scale has 7 notes/pitches, ex. C major scale has pitches C D E F G A B
If one would include a note or a chord thats not from that scale, say, C#, it would result in false sound.
Well what happened to me.
I wrote a piano solo. I enter notes with mouse in Cubase so sometimes i dont really pay attention which notes im pressing or which key im playing in, i go by ear.
First half is in the key C major and for the second half it modulates into a different key which is all right.
But, first i thought that the new key is
E-flat major (pitches C D Eb F G Ab Bb)
Then i noticed that in few verses, the notes and chords include pitch Db ,instead of D. That would be the key
A-flat major (pitches C Db Eb F G Ab Bb)
These pitches, D and Db, doesnt play both at one time so it doesnt sound false, at least to me but maybe im tone deaf who knows.
My question is, could it be that randomly without really knowing it i made a few modulations from E-flat major to A-flat major back and forth?
Theyre changing pretty quickly, something like
0-10 sec.: A-flat major
10-15 sec: E-flat major
15-20 sec.: A-flat major
20-.... sec: E-flat major

Is this kind of fast modulations common in music? Or is it simply false and im weird?
