A concert of sylphs or elves

French composer Erik Satie once wrote a piece called Vexations, in which it's suggested to the pianist that the theme might be played 840 times. Somehow that title hung over me as I headed to Bath for Joanna MacGregor's Chopin Mazurka-fest.

OK, time-wise, performing all 58 Chopin Mazurkas isn't such a herculean task, fitting into, ehem, a mere three hours. Performing them's one thing; how about listening to them? Surely wall-to-wall Polish-folk-dance-inspired piano miniatures on a Sunday morning would be too much of a good thing? Even, dare I suggest it, a bit boring? Coffee was needed.

Caffeine consumed, the Chopin-listening began. In an unbroken flow, with no room for applause, Joanna MacGregor launched into this consuming musical world. As her programme jottings noted, the pieces range from 'wittily joyful', to 'plangently melancholic', 'robustly merry' to 'wistfully delicate'. Played in chronological order, what was most telling was that, once Chopin had got over the initial teething period in this form, they were remarkably stylistically homogenous. Not much of a journey, but the whole was a refreshing experience.

Over to Berlioz: 'There are unbelievable details in his Mazurkas; and he has found how to render them doubly interesting by playing them with the utmost degree of softness, piano in the extreme, the hammers merely brushing the strings, so much so that one is tempted to go close to the instrument and put one's ear to it as if to a concert of sylphs or elves'
