The reason why I made the variations of the theme hard to distinguish is because I didn't want it to sound derivative, boring and repetitive.
The reason for composing a piece in a specific way should never be what the people will think ot the fear to being unoriginal or boring
The more you try to be free by consciously breaking with the past or consciously avoid certain derivations and influnces the more you will be entrapped by strict rules that don't permit originality
Ihmo you should first start with a mind image of what your piece would like to sound and why (a love ballade for someone, an introspective piece, a piece of joy because of something beautiful in your life, a sad moment, your doubts and fear and so on) but you should simply write whatever you feel is the right thing to say at the moment with the music, but free yourself completely from any rules, fear of influence, fear of plagiarization, fear of being unoriginal, fear of being boring, fear of being old-fashioned
You can be free in let your art and originality come out if you're always focused on what your piece shouldn't like instead of what he should like despite deravation, influences copied style and whetever
I'm not saying you're composing with these fears, but it's a suggestion
And remember that music can't help but being derivative
Breaking with the fast, being innovative and new, not being derivative are just illusions that doesn't take in account how our mind and physic of time works
Every piece of this world is derivative
In fact, even the avant-garde music created just for the sake of being innovative and never influenced by the past is completely derivative and completely influenced by the past
Beethoven and Bramhs music was derivative and they aknowledge it and never fear something natural and unavoidable
Debussy, Bartok, Tchaikovsky, Dvorak, Rinmsky-Korsavok, Stravinsky, Schoenberg, Boulez, Xenakis, Berio and even Mozart they always composed derivative music
Let's put this 20th century modernism myth that music shouldn't be derivative, that music can be non-derivative and that being derivative is being unoriginal at rest once and for all
