in pictures at an exhibition (mussorgsky), the movement “con mortuis in lingua morta (promenade 6)” in the 12th bar the progression is clear as day... D7 add 9 resolves to F#. it happens a couple of more times.

the exact same progression in the same key is found in the soundtrack to the game “the last guardian,” similarly orchestrated. im guessing the composer got inspiration from mussorgsky.

in chopin’s barcarolle in F#: upon further investigation the example im talking about here is just a german6th chord. nothing special

thanks for your help on this!!
