Data

The file ./src/Canon/Data.hs contains three Canon data types in increasing abstraction:

• SimpleCanon
• ScalesCanon
• Canon

Utilities

The file ./src/Canon/Utils.hs contains functions to convert the three Canon types into the RealSimpleMusic Score type:

• simpleCanonToScore
• scalesCanonToScore
• canonToScore

Use the Score type as input to the RealSimplemusic conversion functions scoreToMidiFile and scoreToLilypondFile. For examples, see the file tests/Canon/UtilsTests.hs.

Example

See the file tests/Canon/UtilsTest.hs for examples showing the use of simple types, score, and conversion routines.

For more complete examples, see ./src/Canon/Canon.hs, the implemetation files Data.hs and Utils.hs in ./src/Canon/Canon/ and the test files in ./src/tests/Canon/UtilsTest.hs.

For program examples generally, see the files in ./tests, including

• MainTestSuite.hs - test driver
• Canon/UtilsTest.hs - test Canon.hs types and methods
• data/Frere Jacques ...* - midi, Lilypond, and PDF score files rendered using Lilypond.
