When you voice chords for an orchestral piece do you have parallel octaves and fifths not including pedal tones. I've been told to avoid using them if I can.
Nope- I'd avoid those when possible. The thing is, if you follow strict voice leading practices (as was done by Bach and countless others) you should NEVER have parallel octaves and fifths. Some rules can be broken under certain circumstances, but the only instance I can think of where parallel 5ths can be accepted is when you're using a German Augmented 6 chord to a V chord (which you won't encounter a lot). Modern music is such that anything goes. However, since a lot of the tonal music we base our studies off of follow standard voice leading practices, our ears have developed in a way that parallel octaves and fifths sound strange (they stick out to me like a sore thumb because I'm so used to avoiding them). So, it's not that you CAN'T use them, but you should avoid using them if you're striving for smooth voices.
In an orchestral setting, when parts are doubled (i.e a cello part doubled in the bass), parallels are acceptable because the two parts are considered one unique line.
So, in short, you should not use parallel octaves or 5ths, unless you are doubling parts between instruments. Hopefully that made sense, let me know if something is confusing!
