The night I fell in love with Chopin. I had never been a fan of Chopin. That is
not to say that I disliked him; his work had just never spoken to me the way
other composers do. Until yesterday. As per tradition, my parents took me to the
orchestra, which was playing Chopin’s Piano Concerto No. 1 and Brahm’s Symphony No.3 (what you had is not technically wrong but as a classical player I opt for this terminology).
Marie-Ange Nguci, a young French-Albanian pianist was the soloist. The orchestra
was (would remove the adjective ‘briskly’ as could imply that she led ‘too fast’ etc.) led by a visiting conductor; (would be nice for reader’s to be given name of conductor) a young and extraordinary woman. How
impressive she was, literally dancing, while conducting the orchestra without a
single piece of sheet music. But when Nguci started to play, it was as if
everything around me disappeared. The musicians, the stage, the
conductor... - the audience would have disappeared as well if it weren’t for
some people walking in and out of the hall in their squeaky shoes...
But the music was too extraordinary/transcendent/enticing/sublime (alternative adjectives to use instead, it’s a personal preference to not use ‘phenomenonal’ as the adjective combined with ‘too’ is overpowering and takes away from what you’re trying to convey. These adjectives are more suited to describe this experience.) to waste time in antagonisation (more natural) . I was no longer in the (would use ‘the’ here as subtle but effective way to specify the context and tie the reader to the atmosphere you are creating.)
concert hall. The piano was a (removed as contradicts your later words) stream rolling downhill, at times dainty and
light, on others swift and fiery. Always graceful. The strings encouraged her
like a wind rustling through the leaves of the ancient and young trees of a
forest inhabited by spirits of horns, flutes, clarinets.A moment suspended in
time I know I will cherish for a long time.
