Key ideas in How Music Works
- A melody moves by steps (to adjacent notes), leaps (skipping over notes), or repeated notes
- Steps create smooth, connected lines while leaps add drama and sudden changes in pitch direction
- The mix of steps, leaps, and repeats creates the audible shape or contour of a tune
- A melody naturally pulls toward a central 'home note' (the tonic)
- Reaching the home note provides a feeling of stability, resolution, and finality
- Stopping on notes other than the home note leaves the listener waiting for the music to finish
- Distance from the home note creates musical suspense or tension
- Moving back toward the home note releases that tension and feels relaxing or grounded
- Great melodies balance tension (moving away) with release (coming back home)
- Melodies often work in pairs like a conversation: a call/question followed by a response/answer
- The question phrase ends with an upward or unresolved pitch away from the home note
- The answer phrase brings closure by landing securely on the home note
- Internalizing the pitch in your mind and voice bridges listening and playing
- Humming or singing first ensures your hands are guided by your ear rather than random guessing
- Translating a melody from voice to instrument is easier once the contour is steady in your throat
- Notes hitting directly on the pulse give a melody stability and resolution
