Drop the Beat
How AI turns words into music — and text into a human voice. Pick any concept. Many of these play real sound — click “enable sound” up top first. Press Esc anytime for this menu.
Sound is a wave
Every sound — a note, a voice, a drum — is just air wobbling fast. Draw that wobble and you get a wave. Faster wobble = higher pitch; bigger wobble = louder. Enable sound, then drag the sliders to hear and see it.
Pitch (frequency): 220 Hz
How fast the wave wobbles → how high it sounds.
Volume (amplitude): 50%
How tall the wave is → how loud it is.
Shape
The wave's shape = its “timbre” (flute vs buzzer).
A song is layered tracks
A song isn't one sound — it's layers stacked together: drums, bass, chords, melody. Toggle each layer and hear the track build. AI music tools generate these “stems” and mix them, just like a producer.

From noise to music
Remember how image AI turns static into a picture? Music AI does the same with sound. It starts with a hiss of audio noise and, guided by your prompt (“lo-fi, rainy, chill”), cleans it into a musical phrase — step by step. Drag the slider.
Denoising step: 0%
Left = pure hiss. Right = clean musical phrase.
Prompt
“lo-fi hip-hop, rainy, chill”
The words steer what the noise becomes — same as images.

Predicting the next note
One way AI makes melodies: like it predicts the next word, it predicts the next note. Give it a few notes and it continues the tune in a style it learned. Play a seed, then let AI carry on.

Text becomes speech
Type a sentence and AI turns it into a talking voice. Under the hood: it splits your words into little sounds (phonemes), predicts the melody and rhythm of speech, then generates the audio wave. Enable sound and press speak.
Your text
The pipeline
Uses your device's built-in voice for the demo. Real tools (ElevenLabs etc.) sound far more natural.
Why it sounds human now
Old text-to-speech was flat and robotic — every word the same length and pitch. Modern AI adds prosody: stress, rhythm, pitch changes, even breaths and emotion. Drag through the years to see (and hear) the leap.
Year: 2010
2010 — flat, robotic, monotone.
What changed
Newer models predict the natural ups and downs of real speech — so a sentence rises, falls, pauses and breathes like a person.
Cloning a voice
Give AI a short sample of someone talking and it learns a “voice print” — the unique fingerprint of that voice. Then it can make that voice say anything, including words they never recorded. Powerful — and the reason consent matters (next section).
Step through it
1 · A short sample
Just a few seconds of someone speaking is enough for modern tools.

Emotion & style dials
The same sentence can be said a hundred ways. AI voices are steerable: you set the emotion, speed and pitch. Pick a delivery and hear the difference — the words stay the same, the feeling changes.
Delivery
Speed: normal
Pitch: normal
Same words: “I can't believe you're here right now.”
Consent & voice deepfakes
If AI can clone a voice from seconds of audio, it can make someone “say” things they never said — for scams, fake news, or impersonating family. The skill isn't just making voices; it's using them responsibly, and spotting fakes.
Scenario
📞 Scam call
A cloned voice of a “relative” calls in a panic asking for money. Always verify another way.
The rules
✅ Get consent before cloning a real voice. ✅ Disclose AI voices. ❌ Never impersonate to deceive. 🛡️ Agree a “safe word” with family for phone scams.
Who owns an AI song?
You typed the prompt — but who owns the result? It depends on the tool's terms, your plan (free vs paid), and what you asked for. “In the style of [real artist]” is a legal grey zone. Here's the lay of the land.
Check
Free tier
On most tools, free-tier songs are for personal use only — the platform may keep rights, and you often can't monetize. Read the terms.
Sets up Day 5
If you want to earn from AI music, this matters. We'll cover monetizing properly on Day 5.
Why headphones feel 3D
Two ears, two speakers. Send a bit more sound to one side and your brain places it there in space. That's “panning.” Put headphones on, enable sound, and drag the sound left and right.
Pan: centre
Slide left/right — the sound moves between your ears.

Prompting a music tool
Tools like Suno don't need sheet music — they need a good description. A vague prompt gives a thin, generic loop; stack genre + mood + instruments + tempo and the track fills out. Toggle the parts and press play to hear the difference.
Build the prompt
Richness: thin & generic
Beat & tempo
Tempo is the heartbeat of a track, measured in beats per minute (BPM). Slow = chill; fast = energetic. Same drum loop, different speed — drag the BPM and hear (and watch) the pulse change.
Tempo: 90 BPM
Mid-tempo — a steady groove.
Rough guide
A map of genres
Just like words and pictures, AI puts musical styles on a “map” — similar genres sit near each other. That's how it blends “lo-fi + jazz” or slides from pop toward rock. Click a genre to see its neighbours.
Pick a genre
Lo-fi
Sits near jazz and chillhop — mellow, mellow neighbours. Blend two nearby points and you get a fusion.

Lyrics become vocals
The headline trick of tools like Suno: give it words, and it sings them — matching each syllable to a note, over the music. Watch the lyrics light up in time with a melody, syllable by syllable.
Lyrics
“Ci-ty lights are call-ing me to-night”
Same trick — meet AI
Demo uses your device voice as a stand-in singer; real tools sing in tune.
Pulling a song apart
The reverse of layering: AI can take one finished song and separate it back into its parts — vocals, drums, bass, other. That's how remixes, karaoke tracks and mashups get made. Click to split, then solo a part.

Sound effects from words
Not just music — describe a sound and AI makes it: “footsteps on gravel,” “thunderclap,” “sci-fi door.” Perfect for the videos you made on Day 2. Pick one and hear a quick synthesized version.
