Final answer:
Music was indeed published when the Gutenberg-style printing press was being used in Germany.
Step-by-step explanation:
The statement that music was published when the Gutenberg-style printing press was being used in Germany is True.
The invention of the movable type printing press by Johannes Gutenberg in 1436 revolutionized the printing industry in Europe. Gutenberg's press allowed for the mass production of books, which included not only written materials but also musical compositions. With the wider availability of printed music, the demand for music as entertainment and as an activity for educated amateurs increased.
This development coincided with the emergence of a bourgeois class and the unification of polyphonic practice in Europe. Composers such as Palestrina, Lassus, Victoria, and William Byrd were able to disseminate their chansons, motets, and masses to a wider audience, leading to a flourishing musical scene in cities like Venice, Rome, and Florence.
