| Variations |
|
One of the earliest
musical forms. A melody is presented and is then repeated as
many times as the composer wishes but in an altered or changed way.
The theme may be binary (AB) or ternary (ABA).
There are countless ways in which it may be varied. The most
important include:
- decorating the theme with ornaments or extra
notes
- presenting it in the opposite mode (from a major
key to a minor key)
- changing the harmony, rhythm, metre or speed
- hiding the theme by putting it in the bass or
another part
- imitating the theme or turning it upside down
- adding another melody above the theme - known
as a counter melody
- making the theme disappear but keeping the
same harmonies or rhythm
- changing the instruments the piece is written
for e.g orchestra - piano solo
