The aim is to have a straight wheel, not one which plays a scale, so instead focus on tensioning the spoke to get the wheel straight. You just need to get enough tension in the new spoke to pull the wheel back straight. At this point the new spoke should make a 'ping' sound similar to the other spokes, i.e. it should have enough tension not to de-tension in use and come undone.
If you're just installing one new spoke in a well-built wheel, you should only need to touch that spoke to get very close to a perfectly true wheel if you're using modern stiff rims as the rim and spokes will not have undergone plastic deformation. A typical mistake is to change the tension in the next door spokes, which introduces hop. To avoid this I put a strip of tape on the new spoke.
If for example you run an shallow aluminium rim and lose 3 spokes in a crash, likely the rim will have permanently bent. By all means then try to straighten the wheel by replacing the spokes, but in all likelihood the spoke tension needed will be wildly different even on a front wheel (you will feel the tension difference from the spoke key). In cases like this it's best to replace the rim as the wheel is unlikely to be reliable.
But after getting a tension meter the wheel I build are way better now.
Doing it by feel is doable but you will not get the same results as you do with goods measurable numbers.
To replace one spoke and nothing else you can get away not using a meter if the wheel is built properly to begin with (as previously stated)
A tension meter is a tool to have if you are going to build some good, round, true, strong wheels.
It's a stella-azzurra recommendation.
Tensioning by sound is for the master wheelbuilders. Tensionmeters are a bit overrated in my opinion.

If the wheel was straight before and the tension even, then tensioning that spoke until the wheel is true will work. No need to touch the other spokes unless it is necessary.
You need to thoroughly stress relieve that spoke, though.
Who?! Who is the master builder?
Can a master builder play a tune with your built wheel?
What kind of tune would he play if he was a master builder?
If you are musically challenged like me get a tension meter.
