This video is barely a quarter of an hour long, so close you eyes and enjoy. Let the music take you down the river from its origin to the river Elbe to which it is a tributary. The description of the different movements (see below) I found in the comment section of the YouTube video, and edited only slightly. Might make sense to read it first and then listen.
Bedřich Smetana ~ The Moldau (Vltava)
The piece describes the course of the Vltava (Moldau is the German word for Vltava) throughout Bohemia:
0:00 Springs of Vltava – The spring of water gushes from the earth. The two flutes symbolize two streams, which comprise early part of the river.
1:07 Vltava’s theme – The two streams meet and the river starts.
3:11 Forest theme – The river snakes through the forests of Šumava. You can hear hunters calling a hunt on a horn.
4:20 Wedding scene – Polka symbolizes a wedding in the fields that the river is a witness of.
5:34 Night scene – Night falls. In a forest glade, fairies dance in the moonlight. On nearby rocky hills sit old castles and ruins.
8:51 Vltava’s theme
9:50 St. John’s Rapids
11:08 Vltava’s theme
11:37 Vyšehrad castle – The river passes through Prague, already big and strong (picture in the video). Here we can hear another part of Smetana’s piece “Vyšehrad”.
12:30 Vltava is slowing – The Vltava river ends by flowing into the Elbe river.
