Tin whistle
In recent years a number of instrument builders have started lines of "high-end," hand-made whistles, which can cost hundreds of dollars US each — expensive in comparison to cheap whistles, but nevertheless cheaper than most other instruments. These companies are typically either a single individual or a very small group of craftsmen who work closely together. The instruments are distinguished from the inexpensive whistles in that each whistle is individually manufactured and "voiced" by a skilled person rather than made in a factory.
Tin whistle
Gaining popularity as a folk instrument in the early 19th century in the Celtic music revivals, penny whistles now play an integral part of several folk traditions. Whistles are a prevalent starting instrument in English traditional music, Scottish traditional music and Irish traditional music, since they are often cheap (under US$10), relatively easy to start with (no tricky embouchure such as found with the flute), and the fingerings are nearly identical to those on the traditional six holed flute (Irish flute, baroque flute). The tin whistle is a good starting instrument to learn the uilleann pipes, which has similar finger technique, range of notes and repertoire. The tin whistle is the most popular instrument in Irish traditional music today.
