hello

Could we have David's listings of transposition in the Handbook?

The article was written as guidance on how to develop the latest transposition feature in MuseScore found in version 0.9.6.x. The handbook is written for helping people understand how to use MuseScore.

Why do you want to include it?

In reply to by David Bolton

yes,

have had many problems getting the right key signature, but hard to describe in details, since they probably are related to other subjects regarding transposing..... also to and from concert key.

(...but I always end up getting it right.)

Interesting article - I'd never heard of triple sharps/flats!

On a technical note, I read somewhere that you could only apply the diminished and augmented modifiers to perfect intervals - otherwise you should use flatted (or flattened) and sharped (or sharpened). Perhaps this usage has fallen out of favour? I think the usage of dim/aug across all intervals makes logical sense.

I've seen flat and sharp used in guitar chords, but I always heard diminished/augmented in school. Maybe the language differs between genre/instrument? Is it regional? (I learned most music theory in the USA).

I would be interested to see the source, if you remember where you read it.

It was a long time ago - around 40 years ago (in the UK), at the time that I first started playing an instrument and had to learn to read music. It may even have been what somebody told me. I still remember the occasion when a primary school friend (who was lead violinist in the school orchestra - I was double bassist) explained to me about key signatures / cycle of fifths/fourths etc. I soon put down the double bass and started learning the guitar, and I've seen several conventions on chord naming, particularly in jazz, where modifications/accidentals are all over the place! The convention seemed to be to use + or - (superscript) to designate aug/dim of a perfect interval and #/b of others, for example A+5 (with +5 superscript) or C+5b9 (+5b9 super). But it appears to be inconsistent, as I've also seen A #5 (again, the #5 has to be superscript, to avoid confusion with A#). There also seems to be a convention on some jazz charts to use + on its own to mean specifically +5, e.g. A+ means A augmented fifth.
