Check Harmony Rules Plugin Question
When using the MuseScore 2.0 plugin, Check Harmony Rules, I am getting errors that read "open 5" and "open 8". The textbook I am using to study harmony (The Complete Musician by Laitz) does not discuss these rules, at least not using this terminology. Nor did a bit of googling yield anything fruitful.
What are the "open 5" and "open 8" errors? Are they voice leading errors?
Thanks!

Between Bass and soprano:
first one is Parallel 5th: B,F to C,G (Moved in the same direction with 5th interval)
second one is Parallel 8th: F,F to G,G (Moved in the same direction with 8th interval)
Both are contains "open error"; because they are "skips over" more than one chord tone between each voice.
Also: there is a hidden parallel 8th error, between Alto and Soprano. // Soprano: (b),g (a),f; Alto (b), (a)
And: on "V" chord: 3th is missing!

Hi Ziya, Thank you for your help. So what is the hidden parallel error exactly? It's not one that Laitz teaches, but I'd like to be aware of it. Attached is another example with two "hidden 5"s.

First is direct 5th: (both parts moved to same direction) E to F# and A to C# = F#, C#. result is direct 5th.
Second is hidden parallel 5th: G to (g# to) A and D to E -> G, D - A,E is parallel 5th but hidden (by g#).
It is important to evaluate according to which school.
In some schools, the conditions allowed may be prohibited on the other.
