Objectives

• Make your work easier
• Working with Triads can be quite frustrating because
• there is not enough information in Triads to make them reliable
• one is constantly faced with exceptions and "sometimeses"
• One is offered "rules of thumb" and then encouraged to abandon them because
• results are "dull"
• Working with Tetrads is more pleasant and more productive because
• there is no longer any need to "double" notes, having enough to go around
• the Voice-leading is much more evident and reliable
• When we see how Triads are generated from Tetrads
• all the doubling becomes obvious by the process of substitution
• the Voice-leading remains exactly as it was in the Tetrad
• There is also far more to Triads than before, as we discover that
• any Triad can be preceded and followed by any other Triad
• Advanced students will tell you that Harmony becomes simpler when sevenths are "added".


• Get better marks
• We cannot guarantee your getting A⁺s regularly because
• we cannot foresee how your teacher will evaluate your work, possibly attaching more importance to"overlapping", consecutive, or direct fifths and octavesthan we do
• However, you should be able to remain in the B^-to A range fairly easily.


• Understand Harmony better
• Thinking in terms of Tetrads, and generating all kinds of Triads from them
• provides a much better understanding of what Harmony is all about
• will simplify your work with Triads forever
