Flats, Harps & Sharps

15-June-2009-Boyaca-Colom-012

The key of B is occasionally written as C flat, so I presume that it is technically possible for the key of E to be written as F flat? If this is the case, I can’t think of a piece of music written in the key of F flat.

Am I correct (yes I know I am) in thinking that it suits harpists (sometimes) to play in keys like C flat?

I also understand that Havergal Brian would write in E sharp rather than F.

So far as Brian was concerned, it is (I presume) that writing with all those sharps and double sharps gave a somewhat more exotic flavour than the mundane single flat (B flat) of F major. Equally, moving sharp feels to the composer as if he is turning the screw, whereas going flat does the opposite. None of this can of course be heard by the listener.

Part of Richard Strauss’s Metamorphosen uses F flat major, which one commentator has called “a bitter enharmonic parody” of the earlier manifestations of E major in the piece.

But I must admit I wouldn’t have noticed.

In the case of the harpists it is to do with the neutral, up and down position of the seven pedals.

A modern concert harp when “glissandoed” will play a diatonic scale of C flat major when all seven pedals are in the up position. This is why harpists always use a C flat tuning fork to begin their tuning routine. Each pedal has three positions (up, middle and down) respectively raising the pitch of the strings it controls by one semitone. Each pedal is dedicated to altering one of the notes of the scale, hence the C-pedal will affect all the C-strings, the D-pedal all the D-strings, etc. Thus when all 7 pedals are put into their middle position the harp will play a scale of C major, and when in their fully down position, they will play C sharp major. By fiddling around with the pedals (which you will notice harpists do all the time, like some demented organist) they can set their harp to play any sort of scale. It needs quite a brain to do it, but if you look at an orchestral harp part it does have instructions about what to do.

Well, it’s easy, really. Most of the harpists I know are extremely serious.
