Hey Crusoe,
Thanks for listening and glad you enjoyed! Yes, the grace notes do help create that scratching feeling. As to the meaning, the funny thing with art/music is that it can mean many different things to different people. Music with lyrics tend to erase all doubt as to the meaning/intent behind the music, but with instrumental music, the soundscape can paint whatever picture your mind conjures up. That's where titles can be a blessing or a curse. In my case, titles are often given to pieces after I've written them...oftentimes, I don't even have a clue what I'm going to write or what it will end up being until I start putting notes down. The title then helps quickly represent the vision I heard after completing the work.
At other times, I come up with a strong concept up front, supported by a title (recently, a piece I wrote called "What Will Become of Us?" was such an example), which then informs my choices as I write.
In the end though, with music that tells a story, the gammut of different techniques, harmonies, rhythms, timbres, etc. make it difficult to simply represent the entire work with a title. In that regard, I envy the simplicity of pieces named after forms (minuet, chaconne, nocturne, etc.) I've found with my own music, that creative titles tend to gain more listeners...there's definitely a large group that run the other way when you mention: String Quartet No. 2 in 4 movements :) lol
Cheers!
Dave
