Activities:
Activity 1: Pitch Exploration
Using the virtual keyboard (https://www.musicca.com/piano ), explore the difference between
low and high pitches.
Activity 2: Sound Duration Experiment
Record short and long sounds using BandLab. Discuss how duration impacts the experience
of the sound.
Activity 3: Loudness in Action
Experiment with loudness by clapping softly and loudly, observing wave amplitude visually in
BandLab or a similar tool.
Activity 4: Timbre Discovery
Compare sounds of different instruments playing the same note. Reflect on why they sound
distinct.
Reflection
How do you think understanding these characteristics can help us in music and audio
engineering?
By understanding these core aspects, you’ll build a solid foundation to explore music creation and
audio engineering!
In this lesson, you’ve learned that sound is a fundamental element in our daily experiences,
characterized by pitch, duration, intensity, and timbre. Understanding how sound works and how
humans perceive it forms the basis for appreciating and creating music. In the next lesson, we
will explore music as organized sound, diving deeper into how these characteristics combine
to form melodies, harmonies, and rhythms, enriching our auditory experiences and laying the
groundwork for audio engineering.

▶ Sound is a vibration that travels through different mediums as waves.
▶ It has four main characteristics:
▶ Pitch – How high or low a sound is, determined by frequency.
▶ Duration – How long a sound lasts.
▶ Intensity (Loudness) – How loud or soft a sound is, measured in decibels (dB).
▶ Timbre – The unique quality that distinguishes different sounds.
▶ Sound travels through air, liquids, and solids in wave form.
▶ Humans hear frequencies between 20 Hz and 20,000 Hz.
▶ Key Terms: Frequency, Hertz, Amplitude, and Pitch.
