What is the difference between bossa nova and samba?

Bossa nova and samba are both Brazilian music styles, but they differ in rhythm and mood. Samba is characterized by its upbeat, lively tempo and complex syncopated rhythms, often associated with carnival celebrations. In contrast, bossa nova combines samba rhythms with jazz influences, resulting in a smoother, more laid-back sound that emphasizes melody and harmony. While samba is often performed with energetic dance, bossa nova is more introspective and frequently features softer vocals and guitar.
