As requested by faheemabbas3965, here's the Waltz of the Flowers with the Final Fantasy VII soundfont.
The Waltz of the Flowers is just one of the many famous and supremely entertaining excerpts from Tchaikovsky's Nutcracker ballet. It is also among the longest and most substantial of these.
A short introduction sets the stage, with a standout moment being a spectacular, cadenza-like passage for the harp (0:17-0:46).
After the harp's last flourish, the waltz itself begins (0:47).
As we can expect from Tchaikovsky, it is a grand and graceful waltz, scored with beautiful orchestral detail.
There's a delightful Trio section in the middle to provide some contrast (3:00). At first, the tone is delicate and sweet, but soon Tchaikovsky adds some of his trademark sentimentality into the affairs (3:31), although it's dispelled quite quickly and easily (4:03).
In any case, when the familiar main section returns (4:26) it's carried to even greater heights of passion as it nears its conclusion. The way the waltz ends is almost irresistibly thrilling.
