Photograph a page of printed sheet music and hear it played on your instrument. Slow it down, loop the hard bars, and move it into the key you need. ScoreLens is a sheet music scanner made for practice. It reads single-line parts: a violin etude, a clarinet part, a choir line, a page from a method book. A cursor follows the notes as it plays, so you can hear a new piece before you learn it, or check the rhythm you're not sure of. PRACTICE TOOLS, FREE • Hear the part on violin, viola, cello, flute, clarinet, alto or tenor sax, trumpet, horn, trombone, guitar, piano, or a piano guide for singers • Set the tempo in BPM or as a percentage, with a count-in and a click that follows the slower speed • Tap a measure to start there; hold and drag to loop a passage • Tempo, key, instrument and loop are remembered for each piece • Scan several pages in a row and play them as one piece TRANSPOSE AND READ IN THE NEW KEY • Move the part into another key and see it re-engraved; the key is named, so you don't count semitones • Bb, Eb and F instruments: choose written or concert pitch ("A major · sounds G") • Alto and tenor clef for viola, cello and trombone • Print the transposed part as a PDF, free HONEST ABOUT WHAT IT READ Recognition is good on clean printed parts, but it is not perfect. When a measure doesn't add up, a small dot marks it. Tap the dot to hear that bar on a loop and compare it with your photo. Where the app has other likely rhythms for the bar, it plays them one after another and you keep the one that sounds right. "Report a bad result" sends the page to me, and that is how the recognition gets better. SHARE A PART WITH STUDENTS Send a practice track: a short audio file at your tempo and key, with a link, ready for a text or WhatsApp message. Or share the whole part as a link that plays in any web browser, or opens in ScoreLens, for 30 days; stop sharing at any time. Either way you confirm you have the right to share the piece first, and only the notes go out, never your photo. Opening a shared part doesn't use the recipient's free pages. Teachers: write to us for a teacher code that gives your students 30 days of Pro. PAGES WITH SEVERAL STAVES Pick your part, make it louder than the others, or play it on its own. WHAT IT WON'T DO Better to know now than after you download it: • Two voices on one staff won't come out right. It is best on single parts; piano is read too, best on beginner and intermediate pieces. • Handwritten manuscript and tablature aren't supported • Reading a new page needs an internet connection • Check the result against the page before you learn from it FREE AND PRO Free to try: scan your first pages free, with everything above: playback, tempo, loop, count-in, click, transposition, fixing a bar by ear, sharing and the transposed PDF. Pro: unlimited pages; MIDI and MusicXML export for MuseScore, Sibelius, Dorico or your DAW; practice audio (a WAV at your tempo, in your key, with the click); a speed trainer that raises the tempo on each loop; and PDFs without the ScoreLens line. Choose Monthly; Yearly, with a 14-day free trial for new subscribers; or Lifetime, paid once. PRIVATE BY DESIGN No account and no ads. Photos are deleted from the server after reading; a page that didn't read well is kept for up to 30 days to improve recognition, then deleted. Your library stays on your phone.

Stringino
Read full descriptionHide full description
Stringino is a gentle practice companion for pitch and rhythm on the violin. Play from the score and Stringino listens through the microphone, then shows the result in color right on the sheet music. You see at a glance which notes were right and which were off. SEE YOUR RESULTS IN COLOR • Right notes are green. A little flat is blue, a little sharp is red, and a different note is purple. • The pitch you actually played is shown on the staff, with its note name. • The result screen points out what to fix: pitch, missed notes and timing. • A built-in legend explains every color and mark. LOOP A PASSAGE • Tap a note on the score to start from there; tap another to set a range. • Repeat the range 2, 3, 5 or 10 times, or endlessly. • Spots you keep missing are highlighted, and you can retry just that part. TWO PRACTICE MODES • Free tempo: play at your own pace. • Follow the tempo: play with a metronome and check your timing too. TRACK YOUR PROGRESS • Every session is saved in your history. • A graph shows how your accuracy changes for each piece. • Recordings are never saved — only the pitch and timing of the notes you played. LISTEN TO A MODEL • Play the score back with a violin or piano sound. KID-FRIENDLY OR GROWN-UP WORDING • Switch the interface wording between simple language for children and standard language for adults. SUPPORTED RANGE • Covers the violin range, from the open G string (G3) upward. Lower notes, such as on the viola C string or the cello, are not detected yet. A SIMPLE TUNER • Choose the reference pitch (A4 = 440–444 Hz). IMPORT, CREATE AND EDIT SCORES • Import MusicXML and MIDI files. • Tap a note to change its pitch, length or marks. Tap the staff to change the time or key signature. • Try it right away with the five built-in songs. SCAN IMPORT (PRO) • Turn paper sheet music into an editable score from a photo, a PDF or the camera. • Reading happens on our server and continues even if you close the app. You are notified when it is done. • Notes we are unsure about get a colored band so you can check them against your page. • Up to 20 pages per month. Your image is deleted from the server as soon as reading finishes. • Please use copyrighted music only within the scope of private use. PRIVACY • Audio is analyzed entirely on your device. It is never recorded or uploaded. • No account needed. No ads and no tracking. ABOUT PRO (AUTO-RENEWING SUBSCRIPTION) • Scan import is part of Pro: 600 JPY per month in Japan (prices vary by region), renewing monthly.
