How to convert a PDF into editable trombone sheet music

You found a trombone PDF online, or a bandmate handed you a part, and now you want to change the key, mark up the slide work, or pull out a passage to practice. Instead of re-entering every note by hand, you can import the PDF into Flat and turn it into a score you can edit. This guide covers how to import a trombone PDF, what to check afterward, and how to export the finished score.

Importing your trombone PDF into Flat

Importing takes about a minute, on the web or from your phone.

1. In your Flat score library, click New score, then choose Import PDF.
2. Upload your trombone PDF from your computer. On the iOS or Android app you can instead photograph the page, and the in-app scanner finds it, crops it, and cleans up the image.
3. Flat reads the staves, notes, rhythms, and markings, multi-page scores included, and opens the result as an editable score.
4. Press play to hear it, then start editing.

On import, the notes, rhythms, slurs, dynamics, and tempo marks usually come across. Faint or complex passages are the most likely to need a correction, so read through the part before you rely on it. Flat's guide to scanning and importing sheet music lists what it reads.

PDF import works on every Flat account and runs on page credits, so you pay only for the pages you import. One-time packs are 30 pages for $9.99, 70 pages for $17.99, and 300 pages for $49.99.

Refining your imported trombone score

Flat reads most of a trombone part accurately. A few things are worth a look, and a few are yours to add.

• Clef changes. A trombone part sits in bass clef and moves up to tenor clef for high passages, so confirm any clef changes carried over.
  
  💡 Add or change a clef.
  
• Glissandi. The slide produces the cleanest glissandi of any brass instrument, so add them where the line slides between two notes.
  
  💡 Add a glissando.
  
• Slurs and legato. A slur tells the player to connect the notes with air and slide rather than re-attack each one, so check they carried over.
  
  💡 Slur notes.
  
• Articulations and accents. Confirm staccato, accents, and tenuto sit on the right notes.
  
  💡 Add or remove articulations.
  
• Dynamics and hairpins. Add or fine-tune crescendos and diminuendos where you want more shape in playback.
  
  💡 Crescendo and diminuendo.
  
• Grace notes and ornaments. Re-add grace notes and other ornaments that did not survive the conversion.
  
  💡 Grace notes.
  

Sharing and exporting your trombone score

Once the trombone part looks the way you want, share it with a private link so a teacher or bandmate can open it in the browser and edit alongside you in real time. When you want a copy on your computer, export to PDF for printing, MIDI to carry into a DAW, or MusicXML to move it to another program. A common workflow: import a part, transpose it to a friendlier key, then export a clean PDF for the section. See the options on Flat's print and export page.

Getting the cleanest import

A few habits give you a cleaner score from the start. Use the original digital PDF rather than a page you printed and scanned again, since each extra scan adds noise. Keep the file upright and cropped to the music, with one piece per file. Clear, engraved notation reads far better than faint or handwritten pages, which Flat cannot read. The sharper the source, the less you fix afterward.

Why Flat for trombone

Flat runs in your browser, so you can open an imported part on a laptop and keep editing on a tablet at rehearsal, with nothing to install. Playback uses real instrument samples, so you can hear the line as you work, even away from your horn. And because scores live online, a teacher or bandmate can edit the same part with you in real time.
