My music knowledge background
I never studied music in a music school, but I've composed music for some years and know some theory that I've picked up and read about over the years. I do not have much practise with special score symbols and I typically use whatever my score editing software (Guitar Pro 8 at the moment) provides, hence my question.
Context for the question
I composed a piece for two classical guitars which has a section with 20+ measures where 95% of the notes range between E2 and C3 when played on the guitar. Because guitar is a transposing instrument where the guitar sound plays one octave lower than notated in the score, this range is represented in the score between E3 and C4 (middle C which marks the frontier between the G clef and the F clef).
All this to say that almost all notes on this part are notated below the bottom line of the G clef (but above the played E3, notated E4, which is the lowest pitch on a guitar with standard tuning, so below the third ledger line below the staff).
So, I see three options to notate this section in the score:
8va |----------|below the measures of the score section;
- Change to "G clef transposed one octave below" (i.e., the G clef with an 8 below it) (I don't know the standard term for this) on this score section;
- Change to an F clef on this score section.
I know all of them are equivalent, that is not the point of this question.
Which one of the 3 options above would be more "correct" to use in this case and why?
Also, if you could elaborate on which scenarios the other options are typically used in a score, that would be appreciated as well. For example,
8va |----------| may be more suited for brief passages, etc.
