Djembe stands are an invention of the West. Traditional drummers often prefer straps or play in a sitting position. But a drum stand can be very useful:
As you see, there are good reasons to get a stand. Even djembefolas like Mamady Keita use them.
Various types of stands are available. Consider the following to find the one that best suits your needs:
Ease of use
Some stands are easy to set up, others make you miss half the jam session.
Transport and storage
If you need to move the stand around between drum sessions, get one that folds away to save space during transport and storage.
Some stands are for sitting position only. Others have an adjustable height.
Make sure the stand fits the size of your drum.
Most stands hold the drum at a flexible angle, but some don't.
The most expensive one is not necessarily the best for your needs.
