Composers 1 to 20 is a book that combines the subjects of math, music history, literature, and geography. The book gathers a collection of composers across a time span of over 300 years starting from the Baroque era all the way until the 20th Century Modern era. It also covers a diverse grouping of musical styles, genres, and countries. The goal of Composers 1 to 20 is to introduce children to classical music in a friendly and accessible format from a young age. Additionally, it aims to encourage young children to pursue music education. This book is intended for an audience from ages 4 and up.
