The easiest instrument to learn is one that a student is eager to learn how to play; however, some instruments, such as the recorder or harmonica, are simpler in design and may seem easier to learn. When an individual is excited about and has fun with an instrument, they are more motivated to learn and usually acquire their skills more quickly.
One instrument that children can learn as young as age 5 is the piano or electric keyboard. Guitars are a bit more advanced due to the dexterity they require in an individual's fingers. Many other instruments, like the trumpet and flute, can be taught to students as young as 9 or 10 years old. Younger children can play the recorder to practice for more advanced musical instruments.
