Also known as waltz, it is also a kind of dance music in triple time. A folk dance originated in Austria. At first, it was popular in Vienna, and it was popular in Europe in19th century. There are two kinds of it: brisk walking and slow walking. Unlike Mazzuca, which has three beats, its stress usually falls on the first beat of the bar. It is also different from the minuet with three beats. Strauss's masterpiece The Blue Danube is the most famous. Waltz is characterized by lively rhythm and smooth melody, not as soft as minuet. However, it must be clear that music is neither mathematical nor logical, and this difference is only general, not absolute.
Lullaby is also called lullaby. At first, it was a song that the mother sang at the cradle to make the baby fall asleep quietly, and later it gradually developed into a music genre. The musical image of lullaby generally has a warm, cordial and peaceful atmosphere. The tune is calm, slow and beautiful, full of mother's sincere wishes for her children's future. Accompaniment often imitates the rhythm of cradle swing. Because the rhythm of lullaby and boat song is very close, and both of them have lyrical melody and quiet medicinal gas, and have many characteristics of * * *, German composer Richard Strauss adopted Mendelssohn's melody of boat song in his lullaby of Family Symphony.
