I have a guitar track that at the beginning the guy was more timid (with regards to volume) than towards the end.  Overall the performance is good.  I am wondering if there is a tool in Sonar to "level" the volume from beginning to end. 
Is this  what you use normalize or gain for?

So normalize increases the volume of the track such that at the loudest moment during the normalized range, every available bit is used (100% normalization). There are grades down from this. Everything gets louder in equal proportion, the same as when you increase the volume on the track. I use normalization for gain staging into my FX usually. It gives me an easy way to keep different songs hitting the compressors on the tracks in a similar way. The signal strength into the compressors has everything to do with what will get compressed.
 
If you want the track to appear to be the same volume from beginning to end, you could use a volume envelope and adjust the volume of quieter passages up and the louder passages down. Doing this impacts all parts of the peaks and valleys of the wave form in equal proportions.
 
Compression enables you to only impact the louder moments, effectively enabling you to lower the volume only on a range of the volume spectrum rather than equally across the entire spectrum. This can make it so that it's easier to hear the quiet moments after the guitar is struck, for example. The work of a compressor cannot be mimicked with volume fader automation. It is possible to mimic the attack and release part of the compressor (reduce here, increase there), but when you reduce, you reduce all parts of the spectrum equally. It's not possible to only reduce the loudest 20% to 1/2 it's volume increase with a volume fader. When you reduce the volume, all parts of the spectrum are reduced equally.
 
Compressors come in a great variety of choices are usually used in conjunction with volume envelopes.
 
Read up on the compressors you have in Sonar. Hit F1 for help. See if you don't get some ideas of things to try.

I would avoid the normalize button. Put in a compressor on the fx bin and  you can turn on the wave preform view  on the 
bus so you can see what is happening the track. The compressor will tame the high parts and bring up the low parts. Use your ears but the wave preform view is a handle reference to see what the compressor is doing. The  bring the output up a little on the compressor to get an overall level sound. 

I'd throw some volume automation on it.
It'll take a little time to get it right, but the results will be worth it.
That's what I do anyway...

Thanks I think this is what I was looking for.  I have not gotten to the compressors yet I am trying to get the raw file as close as I can before I start the production phase.
 
thx

Ah, yea.  Volume automation.  The title sez it all.  You can rough the volume and then slap a compressor on it to help w/ the leveling.  That is how it is usually done, SOP.  Works great on vocals too.
 
 

Ditto on the volume automation

If the performance on the track changes in tone and well as volume, it might be helpful to cut it into a couple (or more) pieces and put them on separate tracks, and deal with the pieces individually.  This might sound better than trying to squash/expand different parts of a single track that vary hugely from beginning to end.  This is actually a good practice for any track that has significant changes in tone/volume, etc etc.

For what your wanting to do the volume automation is your best bet.

I'd me more inclined to use a clip gain envelope than a volume envelope.
 
Reason? If you intend to compress the track at a later stage then the compressor will be fighting against your track volume envelope, so that whatever setting works during the quiet phase will not work during the louder phase, unless yo automate the threshold of the compressor.
 
Using a clip gain envelope will mean that the signal presented to the compressor is a lot more even in level, and a static threshold will work on both parts on the song
