I was wndering about the sound from my sax, so I took my guitar tuner, which works off of the viberation frequency of the strings on the head to tune your guitar. it works great for that as far as I can tell, but I clipped it on my sax, and when I do a 'C' with primary fingerings, ie just holding the middle top pearl button, it reads a A# however if I use the secondary fingers, the first pearl button, and the middle tone brass key, it is adjustable to perfect tune C. any ideas? is it right, or sdo I need to be concerned? is it just the totally wrong way to see if it is in tune even, or should I take it in and ask a technician what the deal is?
