Draw Sound Waves
Draw a wave-shaped melody. Its height controls pitch, and its position controls time.
Make a melody someone can keep.
Choose a melody, make it yours, and add a message. Your finished music card opens with one link.
A few lines, a melody of your own.
Continuous lines: a line holds one sound and glides between pitches. Draw higher for a higher pitch; leave gaps for pauses.

Can I draw sound waves and hear them?
Yes, you can draw a wave-shaped line on this canvas and hear its musical contour. A rising line produces higher notes; a falling line produces lower notes. Draw a gentle wave from left to right and press Listen. This is pitch drawing: it makes a melody rather than designing the individual cycles of an audio waveform.
What is the difference between a waveform and a melody drawing?
A waveform shows changes in signal amplitude over time. A melody drawing places musical pitch against time. Here, drawing higher changes the note rather than making the sound louder. To design a raw oscillator waveform, you would need a waveform editor; this canvas is for composing notes from shapes.
How is a spectrogram different from a waveform?
A spectrogram shows frequency over time, with brightness indicating energy. It can reveal several frequencies at once, including harmonics. A waveform shows the combined signal amplitude. Use the spectrogram maker to examine an MP3 or WAV recording; use this drawing canvas to create a new melody.
How do I save my wave drawing as sound?
Listen to your drawing, adjust the notes if needed, and choose WAV. Download the audio directly without signing in. WAV preserves the rendered sound; MIDI stores notes for further editing. Sign in only to save a work to your account or create a share link.
FAQ
Does drawing a sine-shaped line create a sine-wave oscillator?
No. The shape controls the sequence of pitches, while the selected instrument controls the tone. A sine-shaped drawing makes notes rise and fall; it does not become a single-cycle oscillator waveform.
Can I draw a waveform with exact amplitude values?
No. DrawMusic does not provide sample-level amplitude editing or raw waveform data export. It is a music drawing canvas for notes and melody shapes.
Why does my smooth line sound like separate notes?
The canvas maps positions to pitches in your selected scale. Continuous lines hold one synthesized sound as the pitch changes; gaps between strokes create pauses. Choose Rhythmic notes in Options for separate note attacks and a rhythm for new lines.
