pianoloverus There are tons of free versions of the inventions on IMSLP.
Yes, but the Henle version is so nice, and more to the point, Iām pretty sure my copy will have my notes from the teacher I worked with back then.
Also, even when I start with IMSLP for a score, if I end up actually working on the piece, I almost always buy a published score because those IMSLP PDFs are generally blurry or otherwise ādirtyā on the page, which I never like.
