One solution is to use a visual metronome and set the beat to the song's bpm, which can be found on http://ja.chordwiki.org/ as well as other sites. Metronomes with blinking lights are the standard, and can be purchased from any music store, found online as virtual metronomes, or downloaded for free as smartphone/tablet apps. One characteristic of physical metronomes you may find useful is that due to the output of sound many of them, especially older models, will vibrate slightly with each tick.

Really curious, how do you get the starting pitch correctly if you're deaf?
