Transposing by changing the clef
Those who transpose at sight can use another method: imagining another clef. The notes stay in their place on the staff; you read with the clef that gives the name you need, apply the new key signature and adjust the octave.
To go up a 2nd from the treble clef, read in alto clef: the first line, which was E, becomes F. The old clefs hardly written today are perfect for this, and each interval has its own.
A complete example with clefs
To go from C major to E major, a 3rd up, read in bass clef: the first line, which was E, becomes G. Add the key signature of E major, four sharps, and adjust the octave in your head, because the clef gives lower notes.
Accidentals follow the same rule as in written transposition: what rose keeps rising. With practice this method allows transposing at sight, a skill expected of orchestral musicians and accompanists.
