＜p＞Around here, we call Tony Dixon's aluminum high d The Modern.  Traditionally, whistles had thin walls which leant towards their "tin whistley" tone (if that's a word :).  In more recent years, many makers, perhaps starting with the late/great Bernard Overton, began making Irish whistles with thicker walls, which produced a more substantial/solid tone.  We still love the traditional thin-walled sound, but sure do love the solid tone that The Modern provides.＜/p＞ ＜meta charset="utf-8"＞ ＜p＞＜span＞New students to Blayne's ＜/span＞＜a href="http://www.blaynechastain.com/i-teach/" target="_blank" title="Checkout Blayne's Online Tin Whistle and Irish Flute Lessons" rel="noopener noreferrer"＞online tin whistle and Irish flute lessons＜/a＞ ＜span＞get this whistle for free when signing up with the annual billing option.  Just mention to us that you've signed up and we'll send you one on the house!  ＜/span＞＜/p＞
