Ammonia Exercise

I wouldn't be so sure about that. Anyway, it's a trifle since in practice one doesn't find intervals that exceed the more than au/etc.

il sense was that of your subsequent posts.

I had posted this interesting pdf, maybe it can also be useful to the author of this topic

anyway Zedef, however, Piston considers them excess, he doesn't even call it the augmented interval... strange.

In the meantime, I am attaching other exercises.

page 10 no.3, on the minor second, the diminished sixth... I would take a look at it

page 10 no.4: I think you are off-topic

Page 10 no. 5:

a) you'd think more of Eb major, F minor would be natural but is not provided for by ascending motion, so perhaps it's better to indicate a modal scale

b) also G+, for example

c) also D- harmonic, for example

d) also E+, for example

I understood the errors in ex. 3: the minor 2nd is not Reb-Mi but Reb-Mib; the diminished 6th Reb-Sibb is not correct because it is a minor sixth, it should be Reb-Sibbb... a special case where the B is diminished three times.

Regarding exercise 4 instead, I didn't understand....why are they off-topic??

Enharmonic equivalents... right?

Yes....two intervals are said to be enharmonic when played outside of a musical context they produce two equal sounds, but in the presence of a musical context they produce different sounds. Example: D-F and C##-E# ....C#-D and Db-Ebb

Exactly Daniele, do you find a correspondence between the dyads of 10.4 and 10.3?

I don't understand you, oracle.... yes, I find a match.......

Ok, I read: "10.4 write the enharmonic equivalents of the previous exercise 10.3"

So, 10.3:

-10.3.a) Db A, I expect in 10.4 something like C# Bbb... I read Db, A

-10.3.b ) Db Eb, I expect in 10.4 something like C# Fb... I read Dbb, Bb

Etc.

I think then that I haven't understood the requirements of the exercise

The exercise simply asks to write two intervals that are enharmonically equivalent to each other.

What is your definition of an enharmonic interval??

Isn't Db enharmonic to C#??

Isn't Eb enharmonic to D#??

Isn't Db enharmonic to Bb??

Isn't Db enharmonic to E??

etc...

I reviewed the exercise and noticed that some are wrong.... but not all... in fact, in ex. 10 no. 4, only the 1st pair and the 4th are wrong; the rest should be correct.
