Sonatas from the "5th year"

For op. 27 no. 2 I would take a look at this topic

I remember opening this topic in the past

An interesting ordering by difficulty...by Liszt also popped up

So, in order according to Liszt:
op 14 n 2
op 10 n 1
op 10 n 2
op 78
op 27 n 2 (even almost among the 10 most difficult)

Mmmm interesting ...

Sonatas 5, 6, 10, 14, and 24 were among those suitable for the former lower piano course; since this is no longer a current constraint, why not explore other works?

I would rely on 2 parameters: taste and the required technical level in relation to one's own abilities.

Is it for an exam? In this case, other things matter too, such as a minimum level of difficulty to meet the expectations of the potential commission.

No I don't currently have exams to take.... It was to start with a manageable sonata let's say

If there are no exams, I would evaluate Op. 14 No. 1; it is not among the easiest, but it doesn't require monstrous technique. Even organists could play it along with the 4th and the 5th. Think about it: if we can play it, even more so a pianist.

Perhaps the right compromise, if you like it, is precisely the 5th

Mmmmm we'll see

Advice from a Beethoven enthusiast and not from a pianist.

Opus 78!

Why?

Because it is a "little" gem of a Sonata and, as often happens with Beethoven's works, since it is considered "minor" in terms of scope and value, it was clamorously snubbed by a certain nineteenth-century criticism and... not only that!

But, in reality, as with the Eighth Symphony, it is a great Sonata.

Like the Eighth Symphony, it is a composition that lacks the heroic and muscular drive, typically Beethovenian, but, just like the Eighth Symphony, it was particularly loved by its composer to the point of responding, to those who asked him, that he much preferred Opus 78 over Opus 27 no. 2. And this is further demonstration that, despite everything, Beethoven greatly preferred this type of music.

Who knows? Perhaps also because this one was dedicated to Thérese, while the other to Giulietta and, the memory was more beautiful, but I think that once again, the composer may have had his own exquisitely musical reasons for stating this.

Still as a non-pianist but as a Beethoven enthusiast, I would exclude the other 3, because compared to Opus 78 and 27 no. 2, they remain on slightly lower steps.

For 5 I've been undecided between 2.... Op 10 no. 1 and op 78....

I would not give up Op. 10 No. 1, but it is a matter of personal taste. Every sonata allows us to obtain in its own way something that we are missing, in many senses.
