Historically Correct Tinwhistle with Wooden Mouthpiece Mellow, Melodic, Slightly Breathy Sound with good Volume Excellent Choice for Both Beginner and Advanced Musicians Tapered Metal Body Fingering Chart, Song Sheet and Box Included Available in Three Colors Available in the Key of D or C Original D Tinwhistle ? Silver Clarke's Original Tinwhistle is still produced essentially the same way as Clarke's first whistle made in 1843. It has a tapered metal bore to bring the finger holes closer together and to increase the range and make the whistle more accurate in the upper registers. The sound is difficult to describe in words, when comparing it to a plastic top whistle most people would say more musical, mellower, a little more character or possibly a less modern sound. Should you buy a wooden top or a plastic top whistle? My answer is to buy one of each. They both have their place, the plastic tops are great if you're playing with other people and you don't have a mic and you need that little extra volume and brightness to get your music out. While the wooden tops excel for solos, and for quiet moments when there's just you and your music. A fingering chart, song sheet and box are included. The Clarke Original Tinwhistle is available in the keys of C and D.
