djm, no need to apologize or you’ll get us all started! It’s not a simple thing…I’m still learning thanks to probing question like on this board.
The simple answer is this: Tuning to a guitar tuner, you’ll be in B Equal. But so what? The difference is imaterial, IMO. Your B chanter is tuned to Just already (the toneholes are sized and spaced accordingly within itself). The chanter reed needs to be set in the seat to accommodate this perfect B of the chanter. The drones then need to be tuned pure to the 4th or 5th of the chanter. Either one is going to be close enough. Most pipers do the 5th. On a D set, I do know pipers who prefer tuning the D drones to the G on the chanter, but very few.
With A=440 being the standard, the bass drone on your B pipes should be B=61.735 c.p.s., the baritone would be B=123.471, and the tenor B=246.942.
The point of your question is tuning a B set to modern standard pitch so you can play with others. Since the chanter is sized to standard modern pitch, so you simply need the right reed set in the seat at the proper depth. This would show up as pretty much right on with all the cheap guitar tuners, even though they are geared for Equal. The difference seems imaterial to me. Other variables will cause it to be off more than the difference. The cheap guitar tuners just don’t have the micro tolerance of the more expensive tuners. The red and green lights (or needle) are only in a general range. You wouldn’t use these for tuning a piano. BTW, the reason why they work so well for guitars is because the tuner is geared to get the compromise right for you, ie, if the saddle and nut on the guitar are right (and the frets and sounding length). Otherwise, as any guitar player knows, you can tune the strings all pure, but that only sounds good on one chord. The next chord sounds off and you have to retune. Pure, or Just, is only good for one key or one basic chord on fixed instruments. It’s tolerable in a couple other related keys too. A well-tuned guitar is a compromise tuning…“a series of tolerable imperfections.” So is a piano. They are both chromatic with 12 semitones.
The long answer, as I understand it so far, and if only to bore you, is this: A=440Hz is only 440Hz at A49 on the piano keyboard. 49 means the 49th key up from the bottom. A=440Hz is near the center of your hearing range. It’s right above what we call middle C on a piano…the piano being the instrument that contains the lowest and highest hearing ranges (for most people). In Equal Temperament, to find the proper number for A#/Bb50 is to multiply 440 x 1.0594631. That means the next note up from A49 would be A#(or Bb)=466.164. 440 c.p.s. means cycles per second. In Equal, all notes are equally off 1.0594631 cents from each other. There is one hundred cents between semitones and 1200 in an octave. Since octaves are pure, the A above A=440 would be A=880. It’s only between the octaves that we compromise. Every octave of evey note on the piano is pure, so this offness is the same within every octave.
I hope this is right. Someone will correct me if it isn’t, or I’ll reread this and see the error myself! ![]()
