And continuning with our "Ithaca" theme, you'll want to check out "Mozart and the Keyboard Culture of His Time" , a presentation put online by the good folks at Cornell University. The site explores, as the title suggests, keyboard practices of Mozart's time.
The site exceptionally well-organized, nicely illustrated, readable, and polished in every respect. There are sections of the site that explore the production, editing, and reproduction of Mozart's works; how Mozart composed; piano practices and instruction during Mozart's time, as well as a delightful section on Mozart and kitsch. Fantastic site for pianists and Mozart lovers alike! Check it out online Here.
