Summarize the following:
To transpose music from C to E flat, you can either move it up a major sixth or down a minor third. A major sixth is 9 half-steps. A minor third is 3 half-steps. If you moved the key signature up a major sixth, you will need to move each note up 9 half-steps. If you moved the key signature down a minor third, you'll need to move each note down 3 half-steps. Once you've identified the correct interval, you can transpose the music without really knowing any further music theory. All you have to do is count the steps. You can buy blank staff paper from any music store. You may also be able to download blank staff paper online for free and print off as many sheets as you need. Set your blank staff paper in front of you with the original music on one side and your blank staff paper on the other side. Use pencil rather than a pen, especially if this is your first time transposing music. Assume you'll make mistakes. You have the choice of moving the notes up a major sixth or down a minor third to transpose the music correctly. Generally, you'll move the notes down if they would be too high for the instrument to play if you moved them up.  For example, a sax can only play as high as an F6. If you have any notes higher than that, you would need to move the notes down rather than up. You don't necessarily need an extensive knowledge of written music to see this. If the transposed notes are falling far above the staff lines, they're likely too high. Test this before you do all the work of transposing several sheets of music, only to find a note that's too high. Scan the music for the highest notes, then move them up a major sixth. If they are too high for the instrument to play, you'll need to move the notes down a minor third. To transpose the piece of music, work note by note, counting the correct number of steps and marking the new note on your blank staff paper. If the original music has accidentals (sharps, flats, or naturals written into the music), ignore them for now. Simply transpose the note as though it wasn't an accidental.  If you're moving the notes up a major sixth, count 5 lines or spaces from the location of the original note. That's where your transposed note will be. If you're moving the notes down a minor third, count 2 lines or spaces down from the location of the original note. That's the new location for your transposed note.

Summary:
Identify the correct interval. Get some blank staff paper. Determine whether to move the notes up or down. Move each of the notes the correct number of steps.
