Rondo A Capriccio Op. 129 is the 73rd stage of Piano Tiles 2. It is unlocked when the player reaches Level 25. With 1055 Tiles per round, it is the longest non purchasable song song in the game (so far) and the 4th longest stage at all. This stage is notable for sudden double tiles.
It is also known as "Rage Over a Lost Penny, Vented in a Caprice".
The song is pretty fast, with 6.67 TPS. The very beginning of the song is not too hard, but then there are double tiles before the first star. The double tiles are very hard and is likely to be stuck before the first star. The second star speeds up to 6.87 TPS and there are a lot of single tiles. And then the doubles are present again right before the second star. The second star speeds up to 7 TPS and then changes from G major to B flat major. And then changes back to G major and repeats the first section and then has double tiles again, and then ends the round.
During the double tiles, using four fingers are recommended. The double tiles occur in each of the three sections of the song.
