This was said, but another way.

The most common transpositions for new players would be:

Guitar in C and Trumpet in D.
Guitar in F (yuck right) and Trumpet in G.

If you put the guitar in Bflat then you get trumpet in C.

So if you ask him the highest note he can play, say it's E, you have to transpose down. You might end up with notes outside the lower end, a lot of beginners have trouble with the low G and A....

The other thing of course is for him to play and play, the top notes come quick enough with practice.
