Ever wonder what makes one piano sound bright and strident while another more mellow and warm? Well my son plays the drums (and piano of course!) and i find it interesting that it’s the attack point that determines frequencies. So… let’s say for example a drummer pulls out a pair of brushes to do a jazz number. Next song he uses sticks for a rock song. Finally, let’s think of soft mallets. Now think about the fact that the drums themselves didn’t change. The rims, the skins – all remained the same. What changed however was the attack point – more specifically the density of the surface. So the brushes have many fibers put together. They ‘swish’ the drums more than hit in part too because the fibres are flexible. The sticks have a very defined strike point but also a firmness to them. The mallets on the other hand are ‘felty’. Each of these accentuate – now this is key – different frequencies that already exist within the drum. The harder the strike point, the more the drum will accelerate the frequencies akin to the mallet. Now in pianos, the hammers are the mallets are they not? They strike the strings – they present the tone. It is at that strike point the tone is established. So if you want different sound, simply change the hammers then right? Well…. sort of. 50% of your tone will be in that strike point and 50% will be the frequencies accelerated within the piano itself. Back to the drum analogy – the mallet can change and produce varying degrees of brilliance but the drum still embodies all of the frequencies… whether you enjoy them or not. So are you stuck with the tone that’s in your piano? No. In the words of the Germans “Vee haf vays unt makink dem talk!” – There are methods to alter the sound – by manipulating the strike point – to change the perceived tone. That’s called voicing.
Quite a number of years ago a friend of mine watched a show on TV about beauty. What was interesting to note was that they took a number of pictures (i hate to say it…sorry i’m not sexist but…) pictures of women of all different shapes, colours, kinds and sizes and showed them to different cultures asking “Point out the most beautiful”. The statistics were interesting… that regardless of culture there is a general sense of ‘beauty’. And before you get your nickers in a knot, let me just say that in North America, they’ve manipulated that concept to the NINES! to the point of disgusting. It’s created a weird box that women are somehow supposed to fit into – regardless of the fact that most do NOT.
I was tuning a piano this morning – thinking of the concept of beauty in tone; how 8 out of 10 of my customers listen for a similar type of tone. I was contemplating what the ‘averages’ were in piano sound – that if you were to play a number of pianos, what most people would find pleasing. Ok follow the rabbit trail here… i was then thinking about connecting a spectrograph (an electronic device that displays a breakdown of frequencies) to pianos that are considered ‘beautiful’ and analysing the correlations of tone. (i know, i know…piano tuning is boring…lol… i have such thoughts when i’m tuning for better part of 2 hours…lol). So after the tone is ‘visible’, then look at the physical makeup of the piano – the felt, the strings, the make and model etc and try and reverse engineer the formula. Why? Well, there’s this thing called VOICING. Voicing is the art of manipulating the piano hammers in such a way as to enhance frequencies or remove unwanted frequencies. When i was young, i thot that each piano company had a certain tone. Yamaha had a tone, Baldwin had a tone, Kawai had a tone, Steinway had a tone… etc… and to a degree, that concept is true. But what MANY people don’t know is that the tone can be altered almost up to 50%. What that means is that you can have an extremely mellow sounding Yamaha – which typically is a brassy bright instrument. Through voicing, you can change the way the fibres of the hammer strike the string. Once this is accomplished, pianos can go from very mediocre to dazzling!
Well… my time is up. I’ll write another blog about voicing some time…promise. And there you’ll understand the basics how-to’s of the process of voicing.
