- Both forró and samba are Brazilian dance music — what's the difference?
- Region and lineup. Forró is Northeastern, built around the sanfona-zabumba-triangle trio on a baião pulse. Samba is Rio's, built on surdo drums and cavaquinho in a batucada stack. One is accordion-led, the other percussion-stacked; they sound like two different countries.
- How do I prompt forró for AI?
- Name the trio and the pattern: "2/4, baião groove, sanfona accordion on the melody, zabumba for bass plus snap, triângulo ringing throughout, nasal open vocal, male-female duet." Putting sanfona and zabumba up front steers the model toward the Northeast instead of reaching for Rio samba.
- The accordion comes out too weak — what now?
- Get specific about the sanfona: write "right-hand long melodic lines, left-hand bass walking the baião bassline" and flag it as "the lead, running through the whole track." A bare "accordion" gets treated as a colour that passes once; naming the left-hand bassline is what makes the baião pulse stand up.
