> It was a challenge to write routines that would keep the computer tolerably in tune, since the Mark II could only approximate the true pitch of many notes: for instance the true pitch of G3 is 196 Hertz but the closest frequency that the Mark II could generate was well off the note at 198.41 Hertz.<p>There are several notes that sounds significantly out of tune, a bit similar to a beginner violinist. Which is kind of poetic in a way. The first computer to play music (in 1951!) had not mastered it yet.
