Detail 01
22-inch diameter, 18-inch depth
Deep and wide, so the fundamental sits low. This is the bass voice in a samba line, not a mid surdo.

Independent shopping perspective

What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Deep and wide, so the fundamental sits low. This is the bass voice in a samba line, not a mid surdo.
Detail 02
Lighter than wood for carrying, brighter and more cutting in tone, and it shrugs off rain and temperature swings outdoors.
Detail 03
Struck with a single beater on one hand while the other hand mutes the head to shape each note.
Detail 04
Built for the traditional Brazilian ensemble role rather than adapted from a drum kit part.
Detail 05
You're paying for a full-size ensemble surdo, not a starter hand drum. It's an investment for a group, not a first purchase.

Product questions
Straight answers to the questions shoppers most often ask about this product.
It's the low drum in Brazilian samba. It carries the pulse under the ensemble while smaller drums play on top. One beater strikes, the free hand mutes.
Aluminum is lighter to carry, cuts more in the mix, and handles weather. Wood shells read warmer and darker. For street work, aluminum is the practical choice.
It's a full low-voice size. Baterias typically use several surdos at different diameters, with the largest carrying the deepest pulse.
It's built for carrying on a strap in a procession. Seated or stand-mounted play is possible, but you'll need the appropriate hardware separately.
