Why this picture above? Music is often built with repetition, however any variety in the way it is delivered is refreshing and can show another side of the story. Basically every book, poem, movie, play and song uses an array of elements to keep the audience's attention and to assist in sharing an emotional expression.
Here are our musical elements:
Dynamics - the use of variations in strength and volume to tell a story.
Rhythm - the variation in beat and subdivision. We will cover most of this in class and in class pieces but you are encouraged to dig deep ad find music that FEELS exciting rhythmically. Then ask the teacher for an explanation if you are curious.
Melody - the tune that you might sing. A single line of notes.
Harmony - multiple pitches played at the same time. Sometimes this enhances the melody by echoing it's movement with nearby notes. Sometimes harmony is that chords that support the melody by playing a different range and rhythm and by providing a foundation for the melody to soar over. This second idea describes what you might commonly call chords.
Timbre - tone/colour. The difference in sound quality despite rhythms and pitch.
Texture - the layers that add more or less complexity. Layers may vary in volume and timbre.
