The speaker introduces the topic and defines the terms 'tone', 'pitch', and 'note', emphasizing that they are often used interchangeably but are not the same.

• A pitch is a specific frequency of sound.
• A note is a written symbol that indicates both the duration and pitch of a sound.
• A tone refers to the quality of a sound, also known as timbre, which is influenced by the overtones of the pitch.

This part delves into the physics of sound and frequency, explaining how we perceive distinct sounds and pitches.

• Sound is perceived when something causes air molecules to move.
• The source of the sound vibrates at a frequency between 20Hz and 20,000Hz, pushing air molecules in a back and forth motion.
• The number of oscillations that happen in one second is called the frequency.
• Each pitch in music is defined by its frequency.

The speaker further distinguishes between pitch and note, explaining how notes provide more information than just frequency.

• Notes include information about how long a particular pitch should be played or sung.
• This duration is indicated by symbols like whole notes, half notes, and quarter notes.
• When you ask someone to sing a note, you're asking for more than just a pitch.

This part explains the concept of tone, demonstrating how it alters the sound of the same pitch played on different instruments.

• Tone is influenced by the overtones surrounding the main pitch.
• The tonal quality of a pitch can change depending on the instrument playing it, due to factors like resonance space and material.
• Asking someone to sing a 'tone' can therefore be misleading or unclear.

The speaker demonstrates the difference between pitch and tone using an equalizer, showing how overtones around the main pitch create different tonal qualities.

• An equalizer shows the active frequencies when a pitch is played, with the largest frequency at the intended pitch and smaller frequencies around it.
• When all other frequencies except the intended pitch are deadened, the result is a pitch, as opposed to a tone which includes the overtones.
• Different overtones are slightly more or less prominent depending on the instrument, influencing the tone.

In conclusion, the speaker summarizes the differences between pitch, note, and tone, and encourages viewers to ask questions in the comments section.

• In summation, a pitch is what you sing, a note is how you sing it, and tone is how it sounds.
• The speaker encourages viewers to ask clarifying questions in the comments if they don't understand.
• She also invites suggestions for further musical topics to explain in future videos.
