2.1 Error Detection
The software detects technical errors in cantus firmi and tonal two-part
species counterpoint compositions. A message is generated for each error
detected, indicating the rule that was violated and, if appropriate, where
the error occurred. The user can analyze the cantus or counterpoint individually,
or can analyze both together, as desired.
The software allows users to disable the application of certain rules.
This is to accommodate users who wish to use different sets of rules. This
is useful because there are several different theoretical perspectives
on certain issues in the literature. The preferences are saved to disk
so that they will persist when the program is closed.
2.3 Random Music Generation
The software can randomly generate a cantus firmus that conforms to
the set of rules that are selected in the preferences. This enables users
to generate cantus firmi for use in writing counterpoint exercises.
2.4 Graphical User Interface
The software has a menu and table-based interface that allows the user
to enter and edit compositions using a mouse and/or keyboard shortcuts.
The interface uses combo boxes to prevent the user from being able to enter
inappropriate information. The user is able to add or delete a counterpoint
from a given cantus firmi so that the same cantus can be used in multiple
compositions without needing to be reentered.
2.5 Read From File / Save To File Functionality
A specially designed file format is used to allow users to save their
work so that they can review or edit it later.
2.6 Online Help
There is an online help that the user can access to gain general information
about the software, instructions on how to use the interface and explanations
of the specific rules which are used in analyses.
