    My tuner went belly up last night and has set itself to god knows what! Anyone know what tuners should be set to? When i play a c its saying an f sharp!

    I think its 442. But praps someone else can confirm that?

    A440 or C523.3 is so called "standard pitch" (

    The BBC "pips" time signal is quite a handy A if you can record it and loop it...

    That being said, the master oscilator in your tuner probably will be running at some multiple of 440 (have you dropped it and could you have disturbed internal components?). If you're lucky, there may be a "trimmer" in there to fine tune the frequency its using...

    Yea OK 440 sits nicely with C on the piano

    Most percussion in your band will be at A=442, so it's probably best to use that.

    Woo. Right on first instincts.

    Thanks Philip. ;)

    So, that's musicians use A=440, drummers use A=442.

    Hmmmm.... :biggrin:

    The obvious question is WHY the percussion department haven't adopted the ISO musical pitch that's been around for 3/4 of a century?

    I'm no expert, but I think A=442 is the general standard these days. I bet your horn was tuned to that!

    Interesting.... ISO 16:1975 (Acoustics -- Standard tuning frequency (Standard musical pitch)) abstract says (having looked it up!):

    "Specifies the frequency for the note A in the treble stave and shall be 440 Hz. Tuning and retuning shall be effected by instruments producing it within an accuracy of 0,5 Hz."

    ( Acoustics -- Standard tuning frequency (Standard musical pitch)

    aren't the musical instrument manufacturers using it (yet)?

    Mind you, 2Hz isn't much to be "different" - well covered up by even slight vibrato :) However, its a nice beat if you CAN hold a note straight...

    442 standard? I thought that was only in football! :)

    As for your tuner, Matt; could be that your battery's on the wane.....

    for anyone interested... the frequency relationship between 2 notes of an interval (in semitones) is governed by:
    where fi is the interval frequency
    fb is the base note frequency
    and i is the interval width in semitones.

    Just in case anyone wanted to know..
    so yes, at middle C level, (261.6Hz) 2Hz is not going to make that much difference.

    As you tune lower instruments though, the impact a 2Hz difference has, increases.

    Has anyone ever called you a BOC before Kepps? :tongue:;)

    Have you consulted the manual? :rolleyes:

    Mine has a button to change the key, so if you select the Key of Bb, it will show a C when the usual cornet tuning note is played. Depressing it twice in succession resets it to concert pitch.

    .... fair point! Find the reset button! Easiest way out. ;)

    440 is the scientific frequency, not 442....... 442 is too sharp :p
    but at the end of the day, so long as the band are in tune................... ;-)
    440... 442............. doesnt really matter... it's a frequency, not a note.

    Having sat behind you in band I am shocked to find out you own a tuner, but not surprised that if you do it doesn't work.
