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.

                     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.
