Not dumb at all. That is a very Scotch Whisky 101 to try at first. Hope you enjoyed it.
Another issue to consider is what type of glass you are using; especially when it comes to aromas. It is best to use a Glencairn glass where there is a narrowing at the top. This will concentrate aromas. Don't have a Glencairn? Try a snifter glass or even a wine glass. If you are trying to nose the whisky using a rocks glass or tumbler, you will have a difficult time trying to discern an aroma simply because the vapors dissipate.
A few other tips for nosing: when you inhale, open your mouth slightly. This will allow some alcohol vapor to pass through and will tone down any "alcohol burn" in the aroma. Also, adding a drop of water (not too much to dilute the whisky) will open up the aroma.
