Horoscope is a collection of studies and performance pieces. In order to learn specific techniques, it is essential to put them into continual practice. For this reason, Bert Appermont has put together a group of interesting and musical-sounding studies, which directly lead into the pieces themselves. He assigned each composition to a different sign of the zodiac and chose two characteristics per sign. As the sequence of the pieces is determined by the order of the zodiac, they are not arranged in order of difficulty.
