Flutes are the earliest recorded musical instruments and to put it simply, yes, they are still popular. They are popular both in the sound that they make and the fact that learning them is fun and not terribly difficult. Although you might not choose to attend a flute concert, just about any musical scores and many popular songs contain parts played by flutes.
Popular, top-40 type songs that feature flutes include Mask Off by Future, Tunnel Vision by Kodak Black, Broccoli by D.R.A.M., and Uptown Funk by Mark Ronson. The flute is also commonly used in Disney movie soundtracks.
Yes, flutes are still popular as they are one of the most beautiful and sweetest instruments. A flutist named Lori Bell has been nominated for Grammy Awards, and she won a global mix award. William Bennett plays the flute warm and smooth. He has been recognized by worldwide organizations and music associations for his flute playing. He even won a lifetime achievement award.
Marcel Moyse influenced modern flute playing, and Jeanne Baxtreeser won numerous awards for her flute playing, including the National Flute Association Lifetime Achievement Award. She is one of the best modern female flutists. Unfortunately, flute players don't command as much name recognition as pianists, violinists, or artists in more popular genres.
