Oh wow — you did that? (Yes, you did.) I loved watching you dive into the Chrome Music Lab Soundwave and Spectrogram tools and then sit with the TeachRock interval chart — very Ally McBeal: curious, dramatic, and delightfully exact.
Task 1: You explored wave shapes and spectrogram bands — brilliant. You noticed how simple, repeating patterns show strong harmonics (they look tidy and regular), while complex sounds smear across the spectrogram. That observation ties directly to the ACARA v9 aim of recognising pitch relationships and timbre.
Task 2: On the Harmony and Interval worksheet you listened, labeled ratios and used words like “pleasant” and “jarring.” Excellent. You’re already seeing the pattern: small whole-number ratios tend to sound more consonant; more complex ratios can feel tense or unstable. Your partner work helped you compare impressions — perfect for developing musical vocabulary and critical listening.
Next steps (tiny, clear): 1) Save screenshots of spectrograms for each interval, 2) Match each screenshot to your adjective, 3) Try one Pythagorean tuning example and note differences. Keep being curious — your ear is learning the math of feeling.
