Arezzo User Manual
Arezzo helps you learn the basics of classical harmony, melody and counterpoint:
Harmony. The rules of the game are to first input a bass
line, and then to harmonize it. This means that you have to choose the
4 notes required per chord for the bass, tenor, alto and soprano lines.
You must proceed according to the chiffrage information that specifies
the chord inversion to be used, located below each chord. The system
can be configured to automatically give you each chord degree.
Melody. Your task is to come up with a melodic voice that
is compatible with classical principles. Once introduced into Arezzo,
for instance in the bass line, you can ask Arezzo to check whether it
is well formed.
Counterpoint. Arrezo is able to deal with first
species counterpoint (note per note, with one note per bar) up to 4 voices.
Enter the voices into Arezzo, for instance in the bass and soprano line,
then ask Arezzo to check if they are correct.
Once you think you created a proper harmonization, melody or counterpoint,
you can check it, ask for advice if you're stuck, listen to it or save it on
the Arezzo server.
Arezzo also offers communication tools that enable:
- e-mail posting of your scores to ask for advice, or to print them;
- sharing of scores with other users for group work ;
- chating with other users using the integrated chat system. We also recommend
the use of voice communication systems over the Internet, such as Microsoft
