Lot's of good points from everyone. Some quick comments to clarify some things as they pertain to BIAB Chord Sheet:
<< I have no idea how to enter a diminished chord in BIAB using the NNS >>A diminished chord is entered into BIAB the same as Standard Chord Display (C,F,Bdim)= 1,4,7dim
<< I see the chord name I know what notes are in said chord whereas if I see a IVm I have to figure out the key signature, find the IVm chord, and then figure out what notes are in it. I prefer to see the chord name up front. >>What is displayed on the BIAB Chord Sheet is determined by what display is set as the default. Regardless of the Chord Display type entered, the BIAB Chord Sheet displays the default setting.
For Example: Default Chord Display set to Standard Chord Display; BIAB can display standard, Roman Numeral, Nashville Notation, Solfeggio, Notation (Do,Re,Mi)or Fixed Do (Italy/Europe) Do,Re,Mi relative to C.
The User can input a mixture of all of the Chord Displays and the BIAB Chord Chart will display the default selection of Standard Chord Display. If there's another default selection, BIAB Chord Chart will display that default.
According to the BIAB manual, Solfeffio or Fixed Do is very popular internationally.
Wikipedia:
What countries use Do Re Mi?
In European music theory, most countries use the solfège naming convention do–re–mi–fa–sol–la–si, including for instance Italy, Portugal, Spain, France, Romania, most Latin American countries, Greece, Albania, Bulgaria, Turkey, Russia, Arabic-speaking and Persian-speaking countries.
<< So...just as an experiment, go input the number symbols from the post I made into BIAB and assume it was written only for piano. As BIAB, and your keyboard for that matter does not have the small zero/degree-looking symbol for a diminished chord how will you get the #1dim chord in. >>1dim does the trick.
<<
It will do the Nashville number system as we as Do-Re-Mi.... it's quite capable of speaking several languages musically speaking.
Are the "several languages" expressed like this?
1-4-5 = C-F-G in the key of C
1-4-5 = D-G-A in the key of D
1-4-5 = E-A-B in the key of E
1-4-5 = F-Bb-C in the key of F
Etc.
>>No. This is all one language. Nashville Notation is a single notation system.
<< The numerals/number system is a cool tool but it's an "in the know" tool because one has to know each key for it.
"Anyone at any musical theory level or anyone with no musical theory knowledge at all or even those with false or incorrect belief in what they think is musical theory can with access to and using the BIAB program can 'see' and 'hear' for themselves with no influence or direction from anyone, complex chords, progressions, dynamics and rhythms using Nashville Numbers."
OR any other way. >>Yes, that's correct but it's irrelevant to BIAB chord entry because BIAB will display the chord with whatever Chord Display option selected.
