Folks, I have Sonar X1 Producer, and have not been able to work on my music for several years, but hopefully will have the time in the near future, and had a quick question.
I have an accompaniment .mp3 track, and was wondering if there was any quick and easy way that I could change the pitch on the entire track?  It seems to me that I was able to do this in the past, but as I said, it has been years since I have used Sonar. 
Any help is greatly appreciated,
Thanks so much in advance!

One simple way is use ctrl and either pull out the track at the end or push it in. This will lengthen or shorten the track. Another is use Audio Snap.  Another is the Process/Transpose menu.

Just to clarify, I don't want to lengthen or shorten it, I want to change the pitch of the entire track, by three whole steps up.  Thanks again for your help!

Than use the Transpose function. The last one I listed. 
 
 

Audacity is your friend for quickly doing this......

Select the mp3 track and try Process->Transpose. The "Amount" is semitones. Be sure to check "Transpose Audio" and for the Type dropdown, either "Radius Mix" or "Radius Mix-Advanced."

Yes, no need to go outside Sonar. The Radius algorithms from iZotope are some of the best. "Radius Mix" is what I'd recommend since you're not doing surround.

But three whole steps up? Isn't that "stretching it" so to speak, too far?

Actually...yes, that is quite a stretch. I read too quickly and thought he wanted half steps. That would give much better results...

From what I understood of the process that shifts pitch, it may leave a bunch of noisy artifacts when moving that far, though others here would be far more familiar with that then me.
 
And I DO recall others as having used Audacity for that kind of thing too, as had been suggested above, while others have also had success working within Sonar's included capabilities.
 
You could always try out both approaches, and see which one gets you closer to what you need.
 
Good luck,
