Getting started in composing, I spent a long time making sure everything "fits" and "goes together"... to the point that its all hopelessly "in tune", lol.
I think parts of my stuff could be construed as "mildly interesting, MAYbe, but just in patches here and there" as the overall whole is harmonically bland.
I finally found one or two internet pages that seemed to be showing examples and exercises in polytonality, particularly bitonality. For the first time, the subject made a small bit of sense.
The given example was with Gm and Em... they share many pitches, but each had something that would be dissonant with portions of the others scale.
I quickly grew bored with looking at a score, and listenign to some horrible midi rendering of it... so I just followed the basic idea of a lead line in higher octave in Em... and the accompaniment in the bass lower down was in Gm.
Sure enough, the experiment was neat. After introducing the simple melody, then repeated with its bass accompaniment (all on piano sound, naturally) I went to the Gm/Em melody/accomp. setup they proscribed... huh. It sounded "weird" to my ears, at first... then? Eh, after 10 listens or thereabouts, okay... I decided I LIKED it when the accompaniment suddenly went from being in Em suddenly to Gm... the slight clash/dissonance... okay, it was useful, I likd the effect.
I could see trying more exercises in this, then trying to apply it to one of my sonata exercises... to try to make it more exciting.
Question: could anyone recomend any other "given examples" other than the given Em/Gm practice example? I am without the "harmonic calculus" everyone here seems to break into when arguing how to modulate from key 1 to key 2, LOL...
my ears seem to like this effect, in small doses anyways... when i first did the "clash" (as I think of it) the melody suddenly had a... I dunno... a slightly funny, or slight confused sound to it... then after a few iterations, it gets to sound "normal" almost... THEN, when I went back to the original "in tune" melody, it suddenly sounded "new" and "bright" again....
I'm thinking I want to get more used to doing this, and try to incorporate it to fight boredom in my longer exercises... but short of knowing WHY those 2 keys were picked for the example, it would suffice for NOW anyways, for other key pairs to play with...
