Final answer:
The interest in music was fostered by various factors and individuals throughout history, such as the invention of the Gutenberg press and the rise of the middle class. Music practitioners from the Low Countries were sought after in Europe, and the emergence of opera in Florence sparked a new musical practice.
Step-by-step explanation:
The interest in music was fostered by various factors and individuals throughout history. For example, the invention of the Gutenberg press enabled the widespread distribution of music, leading to an increased demand for music as entertainment and education. Additionally, the rise of the middle class in society allowed for more patrons of music and composers.
In the sixteenth century, the training of singers and composers in the Low Countries brought a new fluid style to music, influenced by composers like Palestrina and Lassus. Musicians from this region were sought after throughout Europe, particularly in Italy, where they were hired as composers and teachers.
Furthermore, the emergence of opera in Florence aimed to revive ancient Greek music and sparked a new musical practice. This demonstrates how the interest in music by various individuals and social developments fostered the evolution of musical practices.
