Why are there Bossa Novas in the JAZZ family?
Many jazz players use Bossas for creating a variation in the bridge of a swing tune. In fact, some swing tunes are even written that way. Putting all the Bossas in the LATIN family would have made it difficult to switch between Swing styles and Bossas in realtime. So we put two Bossas in the JAZZ family to cater to this need; one straight time and one double time. Just make sure you press TEMPO LOCK before switching over.
