Can we also guess for which type of instrument certain movements were intended? Sometimes we can. The Fugue inAminor (Book I) is obviously not intended for harpsichord or piano because of its sustained notes in the bass. It was clearly conceived on the organ. Bach loved the clavichord above all – I own one myself – but he didn’t like the fortepiano, which he got to knowat the end of his life. Some of the fugues in the Second Book are obviously vocal. A prelude like the one in A flat major (Second Book) is clearly an orchestral piece.
