Hello @Gwendolyn Przyjazna!
I am always interested in pieces featuring „exotic scales“ and modes and so I was excited to find out how your „progressive rock instrumental“ would sound like.
Since you didn’t provide a score I could concentrate on listening: My impression is, that the harmonies sound very smooth together – not as dissonantly as in some of @PeterthePapercomPoser’s Persichetti excercises, for example „Persichetti Exercise 2 - 56 for Clarinet Duo“. Thus, producing a dreamy, melancholic sound where especially the transition section from 01:52 to 02:26 reminded me indeed at Kate Bush!
I must admit that I had to lookup what the Lydian Augmented and the Spanish Phrygian scales are all about. And so I found the reason why they are gentler or even more similar each other than I expected in the pair Lydian/Phrygian: The Lydian Augmented scale is more „darker“ than the traditional bright Lydian mode (which sounds paradoxical at first glance), while the Spanish Phrygian scale sounds much more „brighter“ than the original Phrygian one due to its major third.
You added the tag „counterpoint“ to the piece so that I was curious how a counterpuntual rock instrumental would sound like. But to be honest, I get the impression that for most of the piece, you only had one voice with a melody, while the other instruments accompanied in chords or long notes, so I have to admit that I didn't really understand what you meant by “counterpoint”.
Thank you for sharing, I very enjoyed it!
