Are these two feats compatable?

Do Harmonic Spell (from Pathfinder Chronicles Campaign Setting, quoted below) and Lingering Performance work together? Can I cast a spell, spend 2 rounds of performance and receive the benefits from the performance for 7 rounds?

Harmonic Spell:

Prerequisite: Perform (any) 8 ranks, bardic music ability.

Benefit: When you cast a harmonic spell, you can activate
one of your bardic music abilities as a free action. The bardic
music is incorporated into the spell’s casting time, and the
effect of the bardic music lasts for as long as the spell’s casting
time continues and for 5 rounds thereafter. Activating a bardic
music ability with Harmonic Spell consumes an additional
bardic music use per day, but does not increase the effective
level of the spell being cast.

I cannot say if they work the way you want or not, but I just wanted to mention that the Campaign Setting is 3.5 material, so you should check the Inner Sea World Guide to see if Harmonic Spell was updated to PRPG rules or changed in any way if it was.

No, they wouldn't. Lingering Performance says "The bonuses and penalties from your bardic performance continue for 2 rounds after you cease performing." With Harmonic Spell, you're getting the effects of the music, but you aren't actually performing.

That being said, there's no good way to reconcile that feat to the Pathfinder version of bard song. It burns a use-per-day, but that concept isn't applicable any more. Does it take one round? That makes it much stronger. Does it take one round per round it lasts? That makes it nearly useless.

Yes, but Harmonic spell was updated in the Inner sea World Guide.

"Whenever you cast a spell while you are maintaining a bardic performance, you can maintain the bardic performance for that round without expending one of your rounds of performance for the day. In addition, you can switch from one bardic performance to another as a swift action when you cast a spell while maintaining a bardic performance."

And I see no reason why it shouldn't work with Lingering Performance.

Yes, with the new version, it'd work just fine with Lingering Performance.
