If the chords are the result of music written on four staves, they can only be heard by using the play command. I think that's just pressing p with your cursor in the staff. to stop and return to the place where you started play, press o To stop play and continue from where you stopped, you need to first read the lessons on how to insert a beats per measure and beats per minute in Sibelius. -----Original Message----- From: ddots-l-bounce@xxxxxxxxxxxxx [mailto:ddots-l-bounce@xxxxxxxxxxxxx] On Behalf Of Dimitrios Tsakiridis Sent: Tuesday, March 11, 2008 11:16 AM To: ddots-l@xxxxxxxxxxxxx Subject: [ddots-l] Some questions please Hello all: I have some questions about the navigate on a score of Sibelius speaking. 1. I write the harmony score, and after I want to check my cords. I press the alt+up arrow, or Alt+down arrow, but I listen only the Soprano voice and the basso voice. How I can listen the all 4 voices, for example, Soprano, alto, tenore, and basso? 2. When I write the harmony score, how i can to check for paralles, or for other mistakes? 3. How I can to check every cord separately? Best regards, Dimitrios Tsakiridis.
