This intermezzo is one of Brahms's most beloved late-period character pieces. It is distinct for its rich, introspective harmonic language and its gentle, singing melody layered over complex inner-voice movement.
The primary challenge is maintaining an even, singing tone while navigating the subtle rhythmic tensions created by the constant inner-voice triplet and duplet interaction.
Comparable difficulty and character — good candidates for what to learn next.
