Musical key and mood

Key determines mood? Really?!

It is often argued that with the advent of equal temperament all differences between musical keys disappeared, i.e. C major doesn't sound fundamentally different from Eb major. Yet composers still attribute certain moods to certain musical keys. In part this is probably determined by tradition, and in part it may be influenced by the mechanics of playing an instrument: playing a piece in C major on a piano (using only white keys) is quite a different experience from playing that same piece in C# major (using many black and some white keys) because of the differences between physical location of black and white keys on a piano. Also, bowed instruments will often play an F# differently than a Gb, despite both being the same note on a piano.

So what are these traditional moods associated to certain keys?

This list is based on a list made up by Christian Schubart in his book Ideen Zu Einer Ästhetik Der Tonkunst...
