Let's say I make a melody using Major C as my scale. SO, when I start to write the chord progression do I have to make sure that every note of my chords are on the scale?
Seems like this thread digressed a lil' bit from the original question, although people had helpful things to say.
To answer the question no. You can use non diatonic notes, but I think that makes it more complicated. There are many things you can do to spice up your chordal progressions with diatonic NCT's.
Here is a list of your NCT's (non chordal tones)
1.Apoggiaturas (note approached by a leap and resolved by a halfstep)
2.Passing Tones (just to get from one chordal tone to the next (effective in basslines))
3.Neighbor Tones (moving up or down either by half or whole step and then returning to original tone)
4.Suspensions (General awesomeness. NCT held out for dramatic effect, then resolved down by half or whole step)
5.Retardation (opposite of suspension. Half or whole step up)
6.Anticipation (an NCT that is a chordal member of the upcoming chord)
Just pay attention to your voice leading. This is an electronic music forum so I don't expect anyone to be writing Chorales in four voices, but nonetheless it is helpful to know your NCT's. Counterpoint will help to create opportunities for non chordal tones in your music.
Non diatonic tones are a totally different beast, usually created by secondary functions, modulations, or mode mixture. The last of which I believe is the most likely to end up in dance music.
