The Dombra

The dombra is a beautiful string instrument. They called it the queen of Kazakh instruments. It's got a pear-shaped wooden body with a long neck and two strings. Traditionally people made the strings from sinew but today we are using only nylon ones. The dombra is an instrument with a long history. Many Kazakh families have at least one person who can play it. A man usually play on dombra on its own or use it to accompany traditional songs. It sounds great as part of band, too. Some bands even use electric dombras to create music​.

The Tin Whistle.

The tin whistle is a traditional Irish wind instrument that looks like a small flute. Today people make it from a long narrow brass tube with six holes and a plastic mouthpiece. Irish people have played the tin whistle since ancient times and it is one of the most popular instruments in Irish traditional music. We also call it the penny* whistle because in the past many beggars played it in the streets for money. Today, many musicians play it in many styles of music. The theme song of the 1997 film Titanic, 'My Heart Will Go On', features an Irish tin whistle.
