I know from experience that earplugs actually serve me better in terms of directing my focus inward. But sometimes work is better with music.
When I'm reading or writing, I like things with no words, or in words in a language I don't understand. NO CRESCENDOS. So something like piano sonatas, or even modern composers, or baroque choral music in Latin? We're good. Hell, even tibetan chimes/singing bowls, if it's early and still dark. Chopin nocturnes for when it's actually nox.
But occasionally, scholar-ing is a bit more active. Physically active. Like today, when the Hogwarts butler commandeered a giant chalkboard for me and I spent two hours making this:[1]
I puttered at it for a while, unsatisfied, but really picked up the pace and started enjoying myself when I found the right music. If you're familiar with either of Bob Mould's projects (Hüsker Dü or Sugar) that bracket his two solo albums (Workbook being a lot mellower than BSoR), you'll understand the sort of "I am not leaving the room until I kick this project's ass" mood that I was in. It was also a great relief to be physically moving, stalking from side to side of this board, standing back to see the whole thing, and occasionally getting into the music a bit -- not quite a dance break, but about as close as one gets with a bit of hard-rocking post-punk. So, on the off-chance that you have some more kinetic scholar-ing to do this weekend, enjoy:
[1] "This" being a version of the genealogy of the medieval family that I was complaining about in this post. Believe it or not, this is far from complete: I had to leave out about half a dozen maternal lines because they added lines and messes on the board making the whole thing even less legible than previously. I settled for appending the brides' natal surnames -- something that medieval documents never do,[2] but that at least let me see what lineages were being brought together.
As far as all this mess goes, I'm really interested in the middle lineage, and in particular in a guy in the middle of the middle. But I was somehow driven by an urge to understand how it all fit together. So I made a Thing.
[2] ...except in a one very nifty case here in which the maternal surname becomes the surname for an entire branch of the lineage, for reasons that would make a very interesting research paper, I think.
