Lachner Symphony No.6

[eschiss1]

Alan- well, yeah- I -believe- you won't find much disagreement that successfully incorporating a fugue into other forms (especially "sonata-allegro") is/was not a skill available to many... (Mozart and Beethoven got it really right famously several times, and a few others less famously. One author suggested, iirc, that the best- almost the only- places to try it were the development and the beginning of the coda, and with a few exceptions may have been right- which Lachner did, but lack of proper pacing in music will sink, well, anything.)

Edit: there are undeniably exceptions with effective fugues in the recap. Two of the best I know are out of our discussion range- the finale of Edmund Rubbra's first symphony (if it even is a sonata form) and the first movement of Roger Sessions' 4th (more a mini-fughetta early in the recap, but a good one.)
