Q: I am currently studying Elaine Gould’s “Behind Bars” and on page 30 she states: “Terminate the octave transposition with a corner”. In Finale, octave lines seem to automatically end with a corner whereas in Sibelius the line finishes as a vertical stroke which the writer advises to avoid.
How can I make a proper corner at the end of the extension line in Sibelius, if at all possible?
A: Both Finale and Sibelius by default use line strokes rather than shapes to create both the horizontal extension line and the vertical end “hook” for the Octave up and Octave down symbols and other lines.
Both programs also allow the use of a Symbol to end a line, so you can end a line with an arrowhead, corner or any other shape. The advantage of using vector lines for this is that it allows the engraver to precisely mate the line width of the extension line and the hook very precisely so that the line and hook appear to be an extension of the same line.
