Satb: Voices Out Of Range - Question

Hello, my friends

Learning harmony on my own...I have a doubt why the voices marked in red are too spaced. I'm using a software to help me confirm my errors and it gives me this indication.

Is this correct?

Thank you

The theory is perfectly sound other than the numeric notation of the ii5/3. The only other minute discrepancy I see is the doubling in the V6. The order for doubling goes as follows: Soprano, root, bass, inner voices. The only exception is the doubling of the leading tone, which is not allowed. The leading tone in the key of C is B, so doubling the bass is not an option. If the program is opting for the most conventional part writing, that might be why. If it's not that, then I don't know.

Thanks for the reply, forte1320. :nod:

This is just an exercise and some of the common rules are disregarded, at this point of the studies (I'm reading and making exercises from Arnold Schoenberg's Theory of Harmony). So, some "errors" on doublings and some other things are intencional. But, now talking about the program, the rules are according the classical textbooks and generally, when there's something wrong about doublings, it points a doubling error and not some other problem caused by it. Every error comes along with a brief explanation of why it is an error. In this case, it says the following:

Bass and tenor may reach the maximum distance of two octaves. With open parts, the other pair of consecutive voices should be kept within the octave. With close parts, tenor and soprano should not overstep the distance of an octave.

So, nothing is said between alto and bass. 

Thanks

BTW, a link to the program site...it's freeware and very useful.http://harmonypractice.altervista.org/HPWebSiteEn/index.html
