A fun percussion instrument sold by
Latin Percussion.
A Jam Block is a
woodblock made of hard, lathed plastic. The sound may not be as resonant as an actual woodblock, but it is louder and sharper in
attack and
decay.
If you are a drum instructor and you keep good time, a small (blue colored) Jam Block can be used to
broadcast the tempo of a tune over the din of your practicing
drumline.
The larger, pink Jam Block is actually better suited towards wind band work, having a deeper
timbre with a wider spread of color.
