About these tools

Play, compose, and learn — right in your browser.

Every tool here runs on the Web Audio API, which means the sound is generated locally in your browser tab. There is no server processing your audio, no plugin to install, and no account to create. You can open any of these on a school Chromebook, a phone, or a laptop and it works the same way. The piano uses multi-touch so you can play chords with two fingers on a touchscreen the same way you would on a real keyboard.

The collection covers the full range from casual play to genuine music theory exploration. On the playful end, the Piano and Chord Explorer let you press keys and hear immediate results without knowing any music terminology at all. In the middle, the Arpeggio Player, Melody Maker, Rhythm Maker, and Song Maker give you the building blocks of songwriting — notes, patterns, beats, and layers — organized so that useful-sounding results come quickly. On the theory end, Harmonics, Oscillators, and Sound Waves show you why instruments sound different from each other, what the four fundamental waveforms look like on an oscilloscope, and how adding harmonics shapes timbre. Voice Spinner rounds out the set with a recorder that lets you hear your own voice at different speeds and download the result.

These tools are a free standalone alternative to Chrome Music Lab and similar browser music tools. None of them require a Google account or any other sign-in. Everything that can be saved (Song Maker patterns) uses your browser's localStorage, so your work stays on your device. If you are a teacher looking for music activities that work without sign-in on shared school devices, every tool here fits that constraint.

Compose

🎼

Melody Maker

Create melodies on a 5-note pentatonic grid. Tap cells to place notes, choose Piano, Marimba, Music Box, or Synth, and loop at any tempo. No music theory required — every combination sounds good.

Theory & Sound Science

〰️

Harmonics

Explore the harmonic series with real-time waveform and spectrum visualization. Toggle harmonics 1–16, hear additive synthesis in action, and learn why different instruments have different timbres.

📊

Oscillators

Explore sine, square, sawtooth, and triangle waves with a live oscilloscope, frequency control, detune, and LFO modulation. Free browser-based sound synthesis tool.

🌊

Sound Waves

See and hear all four basic wave types side-by-side: sine, square, sawtooth, and triangle. Mix them together with sliders to explore additive synthesis and discover how combining waveforms creates new timbres.

Experiment

🎤

Voice Spinner

Record your voice and play it back at different speeds. Hear yourself fast, slow, or anywhere between 0.25x and 2x. Download as WAV. Runs in-browser, no upload required.

FAQ

Frequently asked questions.

Common questions about using browser-based music tools, what they can and cannot do, and how they compare to other options.

Do I need an account to use these tools?

No. Every tool opens directly in your browser without any sign-in, registration, or email address. The Song Maker saves your patterns to your browser's localStorage, which means your work stays on your device without ever touching a server. If you clear your browser storage, those saves are gone — but nothing is stored on ToolFluency's servers either way.

Is this similar to Chrome Music Lab?

Yes, in spirit. These tools cover similar ground — a piano keyboard, chord and harmony exploration, rhythm sequencing, melody creation, and sound wave visualization. The main difference is that ToolFluency's tools do not require a Google account and are not tied to any platform's sign-in. The Piano, Chord Explorer, Melody Maker, and Rhythm Maker are the closest parallels to Chrome Music Lab's most-used experiments. The Harmonics and Oscillators tools go somewhat deeper on the synthesis side than Chrome Music Lab does.

Will these tools work offline after I first load them?

Partially. The tools use the browser's Web Audio API, which is built into the browser itself and needs no network connection to generate sound. However, the HTML and JavaScript files are served from ToolFluency's servers, so an internet connection is needed on first load. If your browser caches the pages (most do for returning visits), they will often continue working offline or on slow connections — but this depends on your browser settings and is not guaranteed. For fully offline use, consider using a Chromebook in its built-in Chrome Music Lab app or a native app like GarageBand.

Do I need to know music theory to use these tools?

Not at all. The Piano, Melody Maker, and Rhythm Maker are designed so that anyone can get interesting results immediately without any prior knowledge. The Melody Maker in particular uses a pentatonic scale, which means every note you pick will sound consonant with every other note — there are no "wrong" combinations. The Chord Explorer and Arpeggio Player label every chord for you, so you can learn by playing rather than studying first. The theory tools (Harmonics, Oscillators, Sound Waves) do introduce concepts like harmonics and waveforms, but each tool explains what you are hearing as you interact with it.

Can I export or save my music?

The Piano and Voice Spinner both have a Record button that captures audio and lets you download it as a WAV file. The Song Maker saves your grid composition to localStorage so you can return to it later in the same browser. The Rhythm Maker and Melody Maker play in real-time loops but do not have a dedicated export function — if you want to capture those, use your operating system's audio routing tools (on macOS, Soundflower or BlackHole; on Windows, Stereo Mix) to record what is playing through your speakers.

Will these tools work in my browser?

Any modern browser released after 2018 supports the Web Audio API that powers all of these tools — that includes Chrome, Firefox, Safari, Edge, and Brave on desktop, and Chrome and Safari on iOS and Android. If you open a tool and hear no sound, check that your device is not muted and that your browser has not blocked audio autoplay. Most browsers require at least one user gesture (a tap or click) before they allow audio to play — clicking any key or button on the tool counts as that gesture.

Can I use these tools on a tablet or phone?

Yes. The Piano is built for multi-touch and supports glissando (sliding your finger across keys) as well as playing chords with two fingers simultaneously. The Rhythm Maker, Melody Maker, and Song Maker all use tap-to-activate grid cells that work well on touchscreens. The Oscillators and Harmonics visualizers use sliders that are touch-friendly. Voice Spinner uses the device microphone, which may require tapping an in-browser permission prompt the first time. The main limitation on small phones is screen width — the Piano's full keyboard is wide and may require horizontal scrolling on screens narrower than 480px.

Are these tools suitable for classroom use?

Yes. Because none of the tools require a student account, teacher account, or school Google Workspace sign-in, they work on shared classroom devices, Chromebooks in Guest mode, and library computers. The Melody Maker and Rhythm Maker are particularly well-suited for introductory music lessons — the pentatonic grid removes the possibility of "wrong" notes, and the drum presets give students an immediate reference for genre-specific rhythm patterns. Harmonics and Sound Waves are useful for science classes covering the physics of sound. All tools are ad-supported but contain no student data collection.
