Standards and Conventions


This page deals with formatting and the like. For content guidelines, see the Content FAQ. For more general issues, see what TOEOT is not.

The conventions in a nutshell:

 

 

Caution:

While the conventions we use work well most of the time, there are one or two annoying traps we haven't solved yet.

 

When you see Bb, it means B flat. The octave may be implied or may not, depending on context. It does NOT mean two notes. And similarly Ab etc..

 

When you see B b it means two notes, the B two octaves below middle C followed by the B above that. And similarly A b etc..

 

It doesn't happen often, but it's a trap.

 

The other trap is whether the octave is implied or not when you see a capital letter on its own. If we say c' that always means middle C, but if we say (as we just did) C on its own that might mean the C two octaves below c', or it might just mean C and we haven't said at which octave.

 

The context should make it plain which we mean, and we hope it always does. That's up to the writer. We hope you'll soon get the hang of it!

 

(Or if you like, C could mean a note or a pitch class - no let's not go there....)

 

Actually, one of the main motivations for this site was the problem that so many sites do simply give pitch classes - including and notably most Wikipedia articles. Such a tuning is better than nothing, and also better than a wild and possibly inaccurate guess as to the correct octaves, so you'll find them here too. But ultimately, we want to give all of them in full string-by-string modified Helmholtz notation, to remove any ambiguity.

 

 

Fingerboard extensions and other string length weirdies

 

If a guitar or bass has a fingerboard that extends one or more strings (most commonly the bottom one(s)) past the normal head nut where most of the strings stop, it gives us a problem. Should we quote the tuning of the extended open string, which is what you get if you just pluck it, or of the string as if it ended at the normal head nut, which is a better indication of what you get if you fret it? No, we don't know either! So the standard is:

 

 

And the same for sitars and banjos which have some shorter (frettable) strings. Resonant strings which are never fretted we just quote the open tuning regardless of length. See fingerboard extensions for more details.

 

 

Why don't we just use scientific pitch notation instead of Helmholtz?

 

Basically, 'cause we're guitarists at heart, many of us anyway. So A7 means A - C# - E - G to us. More serious for this site, C6 means a whole family of popular tunings. But we've been tempted sometimes. We just had to flip a coin, and Helmie got up.

 

Also I guess D10 could mean the Scientific Pitch Notation for a note that a bat might like, but here it means a pedal steel guitar, or maybe a chord... anyway, as we said, Helmie got up as the standard pitch notation here. The purist might also note that, strictly, the digits in Scientific Pitch Notation should be subscripts... but few people use those.

 

Helmholtz was designed for musicians, while Scientfic Pitch Notation was designed for acoustics and audiology Either works well for both purposes and both notations are used for both purposes, depending mainly on the background of the author.

 

Neither of them is wrong, but both have their fans and some of these even wrongly think that the other is quite useless. It takes all types. See modified Helmholtz notation for a conversion table from one to the other.

 

 

Why don't we just list the strings as numbered?

Good, good, good question!
