Nothing quite like a good improv on your favorite instrument :) I felt this one better, probably because it wasn't clockwork like your last piece. The use of chromatic notes was a little forced at around 3:20, but the rest was clever use of chromatic-ism. I like the way you stuck with the key of Bb/Gmin, I haven't heard music in that key quite played like this in a very long time. The jazz chords at just shy of 11:00 didn't seem so much impact-ful but they seemed like a device to go a little atonal for a couple minutes which seemed to work.
There's definitely a few themes here that could be developed into a song if you're needing inspiration. I'd encourage that, it's an easy way to make more original music by looking at your own songs and seeing if there was something that you wanted to develop upon and establish. When I write symphonies including a harp part, I almost always want to write a song for harp and/or bass clarinet just based off that theme.
*plug alert* Examples of where I employed that tactic, Blissful Venture and Liam's Lullaby, Theme of Disturbed Wind and Trust in Despair, Symphony Allegro and Journey Through a New World, Burnt Okra and Through The Swamp. The infinite possibles in music, it's fun really :D
There's definitely something good from this improv and I enjoyed the mostly clever use of the chromatic notes. This song's unique; nice work Chad. Seriously though, consider maybe writing a song based on something from this session. It's a really satisfying feeling, expressing yourself through a creative work that you enjoy... I'm glad NG exists and allows amateurs to do so.
Thank you, guy. Everything I play is actually improvised. Kind of like channeling my thoughts and feelings into a audio journal. Only way I could replay it would be if I recorded the notes with midi.
