Most children are ready to start when they are between 22 and 30 months of age, but every child is different. Toilet training usually becomes a long and frustrating process if you try to start it before your child is ready.
Brass Instruments and Music in Antiquity and the Renaissance Brass instruments have been around for a long time. Some of the earliest examples of brass instruments were straight trumpets made of wood, bronze, and silver, such as the salpinx found in Greece, and the Roman tuba, lituus, and buccina.
Best Answer: There are many differences between the instruments though most brass players often treat them as more or less similar instruments. The biggest difference is the internal bore-profile. Trumpets have what is called a cylindrical bore profile. A cylindrical bore is a bore in which the sides of the tubing, excepting in the bell and lead pipe, are parallel to each other.
