What is the best way to tune a snare drum?

Response:
The best way to tune a drum depends on which system the drum uses for tension. Newer technologies such as Dialtune's cable tuning system allow a drummer to quickly and evenly tune a drum head by turning separate dials for the top and bottom head. 

Traditional lug and tension rod drums use a drum key and require more attention to detail. For these drums, start by getting all tension rods finger-tight. Bring the snare drum up to tension with a full turn of a drum key of each one, moving in a star pattern around the drum. Use a drumstick to tap around the drum by each tension rod and listen for a consistent sound. 

Once you have the overall sound in the range you’re looking for, test the pitch by tapping around the drum. For the snare’s resonant head, detune it like the batter head. Tune it ‘tabletop tight’: so flat you could confidently rest a drink on it (don’t do this, though). Bring up each tension rod another quarter turn. You want to hear the wires, but not so much that it overwhelms the attack. Tap the head beside each tension rod, then start to even out the pitch with the tension rods so they all match.
