Pro Trumpet Simulator

Click any note pad on screen or use keyboard keys — Q W E R T Y U for white notes (C D E F G A B) and 2 3 5 6 7 for black/sharp notes. Press Space for a long sustained C note. Use number keys 1, 2, 3 or click the valve buttons to toggle valves and change the pitch. On mobile simply tap any note pad directly.

Just like a real trumpet, each valve lowers the pitch by a specific amount — Valve 1 lowers by 2 semitones, Valve 2 by 1 semitone, Valve 3 by 3 semitones. Combinations create more shifts — Valves 1+2 give 3 semitones, Valves 1+3 give 5 semitones, all three valves give 6 semitones. The valve combination name and semitone shift are shown below the valves in real time.

The Mute button simulates a trumpet mute — a physical device inserted into the trumpet bell to change the tone. When Mute is ON, the sound becomes more nasal, thin and suppressed using a low-pass filter. This is commonly used in jazz and orchestral music. Click the Mute button in the toolbar to toggle it on or off.

Switch to Record mode from the toolbar. Click Start Recording and play any notes — everything is captured in real time using your browser. Click Stop when done and listen to the playback using the built-in audio player. Click Download to save as a WebM audio file. Share it on WhatsApp or social media as a voice note.

12+ songs are available across 4 categories — Classic brass pieces include Bugle Call, When the Saints Go Marching In, Reveille, Taps and Royal Fanfare. Jazz includes Blues and Swing melodies. Bollywood includes Tum Hi Ho and Kesariya. Folk includes Sa Re Ga Ma. Switch to Songs mode and click any song to hear it played automatically on the trumpet.

The Vibrato slider controls the depth of pitch wobble — higher values create a more expressive wavering sound like a professional trumpeter. Set it to 0 for a clean dry tone. The Octave control shifts all notes up or down by one octave — Octave 3 for deep bass trumpet tones, Octave 4 for standard range and Octave 5 for high bright notes.
