• 🎼 Online Harp Tuner

    Tune your harp using your microphone, check pitch accuracy, or play reference notes for individual strings.

    1. Tuning Settings

    The 34- and 26-string presets are illustrative note ranges. Actual lever harps vary in their lowest and highest strings. Select the appropriate notes for your instrument.

    2. Live Harp Pitch Detector

    Detected Note — Start the microphone and pluck a string
    −50 cents−250+25+50 cents

    Waiting for a note

    —Detected Frequency
    —Target Frequency
    —Pitch Difference

    For best results, pluck one string at a time, let other strings become quiet, and position your microphone near the harp without touching it. Microphone access normally requires HTTPS and browser permission.

    3. Select a Harp String

    Choose the string you want to tune. C strings have red markers and F strings have blue markers. In Selected String mode, the tuner compares the detected pitch against that specific note.

    4. Tune by Ear

    Play the selected string's reference pitch and compare it with your real harp. The reference tone is synthesized and may sound different from a harp string, but its fundamental pitch is suitable for comparison.

    Stop the reference tone before using microphone detection to prevent the tuner from measuring its own playback.

    5. How to Tune Your Harp

    Step 1: Select the string you want to tune.
    Step 2: Start the microphone and pluck the string gently.
    Step 3: Read the tuning meter. A negative cents reading means flat; a positive reading means sharp.
    Step 4: Carefully adjust the tuning pin using the appropriate harp tuning key, then pluck again.
    Step 5: Repeat until the meter is centered and the pitch is stable.

    Safety tip: Use the correct tuning key, make small adjustments, and avoid forcing the pin. Consult your harp's manufacturer or a qualified technician if you're unsure which pin to turn.

  • An Online Harp Tuner helps harpists and beginners tune their instruments using a microphone or reference tones directly in their browser.

    Whether you're tuning a concert harp, lever harp, or smaller harp, this free online tool can help you identify notes, check pitch accuracy, and make adjustments to individual strings.

    How to Use the Harp Tuner

    Select the string you want to tune and allow your browser to access your microphone.

    Pluck the string gently and watch the tuning meter. The tool displays the detected note, frequency, and how many cents the pitch differs from the target.

    A negative cents reading means the string is flat, while a positive reading means it is sharp. Aim to bring the meter close to the center.

    Tune Your Harp by Ear

    You can also play a reference tone for the selected note and compare it with the sound of your harp string.

    This is helpful when practicing pitch recognition or tuning without relying entirely on a visual meter.

    Concert Harp and Lever Harp Tuning

    The tuner includes a 47-string concert harp reference range and smaller harp range presets.

    Since harp models vary in size and tuning, you can also select individual chromatic notes to match your instrument.

    For lever harps, follow the tuning instructions recommended by your instrument's manufacturer, including the appropriate lever positions.

    Understanding Harp Tuning Accuracy

    The tuning meter measures pitch differences in cents. There are 100 cents in one semitone in equal temperament.

    Small differences can affect how strings sound together, especially when playing chords or sustained harmonies.

    Harp Tuning for Musicians and Producers

    Harpists can use this tool before rehearsals, recording sessions, lessons, or performances.

    Singers, songwriters, and producers working with live harp players can also use the reference tones for pitch matching and musical preparation.

    Tip: Tune one string at a time in a quiet environment, and allow the note to ring clearly before reading the meter. Make small tuning adjustments and check the pitch again to avoid overtightening or breaking a string.
