About the Presenter

"I see people going to college for 14 years studying to be doctors and lawyers.

I see people getting up at seven-thirty every morning going to work at the drug store to sell Flair pens.

But the most amazing thing to me is I get paid for doing this."

- Steve Martin in Let's Get Small

I can relate to Steve Martin's sentiment:

What is counterpoint?

"The relationship between voices that are interdependent harmonically yet independent in rhythm and contour"

Tip: For a gentle introduction to counterpoint, check out the Species Counterpoint article by Nicholas H. Tollervey

@JavaFXpert

Counterpoint example

@JavaFXpert

Listen for interdependent harmonies and independent rhythms & contour

Giovanni Palestrina

Text

Italian Renaissance composer of sacred music

• Created Palestrina-style counterpoint
• Best known 16th-century representative of the Roman School of musical composition
• Influenced music of composers such as Johann Sebastian Bach

@JavaFXpert

Johann Joseph Fux

Born in Austria, Johann codified Palestrina's techniques in the 1700s, calling it species-counterpoint, mainly for teaching students. 

• Published in Gradus ad Parnassum
• Describe valid pitch and rhythmic relationships between notes
• Influenced music of Hayden, Mozart and Beethoven

@JavaFXpert

Composers such as Chopin were indirectly influenced by Johan Fux

Exploring Modes

Using the mode selector

@JavaFXpert

Composing in Dorian mode

Start/end the cantus firmus with a D note and select Dorian mode

The same idea holds true for all modes:

 in Dorian mode

Changing the Rules

Examine the counterpoint rules and results of altering them

@JavaFXpert

Modifying counterpoint rules

There are 70+ counterpoint rules, categorized by importance, that may be toggled to see their effect on the counter-melodies

Toggling a counterpoint rule

One such rule is to avoid unisons in two-part counterpoint.  Here we've toggled it so that the rule is not in effect.

The effects of disabling the avoid unisons rule

Here is our most recent composition before disabling the rule:

Here is the composition after disabling the "avoid unisons" rule:

Note that the final measure now contains D notes in unison, and that most of Melody 2 has changed as a result.
