comment How do I practice (vocal) pitch without an instructor?
There are lots of computer software and mobile apps that can give you real-time feedback on your pitch accuracy. You could try practicing singing while using one of those.

comment Vocal tuning (metering, not autotuning)
Shameless plug follows: Sing-inTuna, an iPhone app I wrote to help me practice singing. Shows several different tuning markers that respond in under 100 milliseconds with an accuracy of a maybe few cents. It's in the iOS App Store.

comment Color coded spectrum analyzer
I wrote an iPhone app that does something like that. For clean monophonic audio input, it draws a line where a note should appear on a grand staff, and colors that line green for in-tune, red for sharp, and blue for flat. You end up with a line graph of the note pitches, colored for pitch. It's called Sing-inTuna, in Apple's App Store.

comment When I play the C chord, why does the electronic tuner indicate that it is a G chord?
+1 : This is a common misconception about how electronic tuners work. I develop tuner apps, and do get this question occasionally.

comment Tuning a tuning fork?
@idober : I used multiple tuner apps, including the Peterson strobe tuner, ClearTune, plus (shameless advertisement) my own inTuna and iChromatic Strobe Tuners, and on three different iOS device models (in case the audio sample rate clock was way off on one of them). They all said 8 cents sharp, +- 1 cent. (I also calibrate my own apps against WWV.)

comment Tuning a tuning fork?
The package said 440, which is what I wanted. I wonder if someone put a fork for a European tuning or something in the wrong box?
