The theme song of Titanic-The Overture of My Heart Eternity played by Irish whistle uses Irish whistle, also called Irish whistle, also called penny whistle and tin whistle. In fact, because it is the soundtrack of the film, and the sounds of various instruments are synthesized together in the later stage, the timbre will be more different from the actual instruments. In addition, in the soundtrack of Titanic, many of them are actually Irish elbow bagpipes, which have somehow been misrepresented as Scottish bagpipes. So, I suggest you stop shorthand the names of these instruments and don't lose this elbow.
Their differences are as follows:
The first difference is that the Irish whistle, like a whistle, blows vertically like a flute, but the timbre is like our bamboo flute, which is easy to distinguish;
Then there are Scottish bagpipes and Irish elbow bagpipes, which are similar in tone, but very different.
Generally speaking, the sound of Scottish bagpipes is more "sharp", high-pitched, divergent and intense, which is very suitable for the characteristics of military music;
Generally speaking, the sound of the Irish elbow bagpipes is more "mellow", concentrated and mellow, with distant, weak but deep sadness.
Personally, I feel that the tune of Titanic is very general. I recommend a memorial danoite by Luar Na Lubre, which starts with an Irish elbow bagpipe. You sang well in the back. Listening to this tune, you feel that the world is so lonely and the universe is so far away.
