Timbre & Articulation

This lesson is part of the Fundamentals of Sound & Music module.

Objectives

• Student will be able to notate and interpret/define various articulation symbols.
• Students will be familiar with ADSR sound envelopes and their components.
• Student will be able to relate different aspects of the attack envelope with perceived articulation and/or dynamic.
• Student will understand the relationship between pitch, loudness, and timbre.
• Student will be able to derive the harmonics for specific wave shapes given a fundamental frequency (triangle, sawtooth, square).
