Answer:
The Moldau River, or in Czech, Vltava river.
Step-by-step explanation:
The Moldau is one of the six symphonic poems composed by Bedřich Smetana in his work called "Má vlast" (My homeland). The Moldau piece is about 13 minutes long and in the key of E minor. It describes the journey of the Moldau river, starting from two small springs, the Cold and Warm Vltava, to their merger into a single stream, its course through the woods and meadows, farmlands, until it reaches Prague, and then vanishes into the distance, ending at the Labe.
