    Play trombone notes online, explore the seven slide positions, practice scales, and record brass melodies in your browser.

    1. Trombone Settings

    2. Interactive Trombone Slide

    Currently Playing — Choose a slide position and harmonic

    Select a slide position from 1 to 7. First position is fully retracted, while seventh position is extended. Each successive position lowers the pitch by approximately one semitone for a given harmonic.

    Choose a Harmonic

    The slide illustration is a simplified position selector. It does not simulate continuous physical slide movement, embouchure, or the precise tuning adjustments required on a real trombone.

    3. Play Trombone Notes

    Click or hold a note to play it. These buttons cover a practical selection of pitches from E2 to B♭4. The slide display updates to a possible position and harmonic when a matching basic fingering is available.

    4. Trombone Scale Finder

    Blue outlines indicate scale notes; gold outlines indicate roots.

    5. Trombone Melody Recorder

    No trombone melody recorded yet.

    Record note timing and durations, then listen to your melody. Recordings stay in the current page session. This version does not export WAV or MIDI.

    6. Computer Keyboard Controls

    Press 1–7 to select a slide position. Press Space to play the selected harmonic. Use A S D F G H J K L ; Q W E to play 13 consecutive chromatic notes beginning at the selected keyboard starting note.

  • A Virtual Trombone lets musicians, singers, songwriters, producers, and beginners play trombone notes directly in their browser without needing a physical instrument.

    Whether you're exploring brass melodies, practicing scales, or learning how trombone slide positions work, this free online trombone provides an interactive way to develop musical ideas.

    How to Use the Virtual Trombone

    Click or tap the note buttons to play individual trombone pitches, or use the interactive slide to explore different positions.

    Choose between tenor and bass-style synthesized trombone sounds, adjust the volume, and experiment with different brass tones.

    Learn Trombone Slide Positions

    Unlike trumpets, trombones use a movable slide to change the length of the instrument's tubing.

    The virtual trombone includes seven slide positions, allowing beginners to explore how extending the slide generally lowers the pitch.

    Different notes can also be produced at the same slide position by changing the harmonic played.

    Practice Trombone Scales

    Use the built-in scale finder to explore major, minor, pentatonic, blues, and other musical scales.

    Highlighting the notes can help with pitch recognition, ear training, and developing melodies in different keys.

    Explore Trombone Sounds and Articulation

    Switch between classical brass, warm jazz, bright brass, muted-style, and synthesized trombone tones.

    Adjust breathiness, vibrato, and articulation to experiment with how different sound characteristics affect musical phrases.

    Virtual Trombone for Singers and Songwriters

    Singers can use the virtual trombone to practice matching pitches, recognize intervals, and strengthen their musical ear.

    Songwriters and producers can experiment with trombone melodies, brass riffs, countermelodies, and horn arrangements for jazz, funk, R&B, soul, gospel, pop, and hip-hop productions.

    Record Your Trombone Melodies

    The built-in recorder captures note timing and durations so you can listen back to short musical ideas.

    You can also copy the note sequence for reference when practicing, composing, or arranging music.

    Tip: Start by exploring the seven slide positions using the same harmonic. Listen to how the pitch changes as the slide extends, then try playing a simple B♭ major scale to practice recognizing different notes.
