To know the piano is to know the universe. To master the piano is to master the universe. The spectrum of piano sound acts as a prism through which all musical and non-musical sounds may be filtered. The grunts of sheep, the braying of mules, the popping of champagne corks, the sighs of unrequited love, not to mention the full lexicon of sounds available to all other instruments-including whistles, scrapes, bleatings, caresses, thuds, hoots, plus sweet and sour pluckings-fall within the sovereignty of this most bare and dissembling chameleon.
