Haydn to establish the four of the symphony.

Haydn helped to establish the four movements of the symphony.

Explanation:

     The most important sections of Haydn's instrumental music are symphonies and quartets. The first symphonies, which did not survive in the repertoire, date from the 1760s. They are used in them elements of Baroque music, combining, in small orchestras, wind instruments and strings. As for the structure, Haydn soon adopted the division into four movements: allegro, andante, minuet and second allegro.

the correct answer would be "the amiens cathedral"

c, d, e, f, g, a, b, and c.

sometimes western music will also use solfege. the names of these are do ra me fa sol la si (or ti) and do.

to indicate a note a half step higher or lower then the original note, you would say c # (for a half a step above c) or bb (for half a step below b)
