This is an editorial from The Independent weekly magazine, published on August 15th, 1912. I don't know the author; the editorial is not signed, but my guess is that it is Hamilton Holt. Here is a link to the article, the photos for the contest, and some other information, if you are so inclined.

This is an article from 1982, written by Daniel H. Resneck for American Heritage. It focuses on Alice J. Shaw, one of the earlies recorded whistlers and an inspiration for whistling women, breaking the taboo that "Whistling women and crowing hens, never come to good ends."

Here is an excellent article on Alice J. Shaw that seems to fill in many of the biographical gaps in her life:

So far, this is my favorite article written about whistling. It was written by Noel Coppage for the May, 1970 issue of Stereo Review. It covers a lot of the great whistlers from the advent of recorded music through the early 20th Century. Has whistling vanished? Is there less whistling now than there was 50 years ago?

This was a great find on the many facets of whistling. T.F. Thiselton-Dyer was a folklorist and in this paper, he talks about many things related to whistling: mythology, superstition, folklore, drinking cups, whistling competitions, drinking contests, whistling oysters and much more.

The previous episode on Peter F. Ostwald's paper was just a little taste. Now we get into his real specialty: psychology. Ostwald explores the methods of whistling, what the whistler experiences, what the listener experiences, some forms of abnormal psychology and much more.

We continue our exploration of whistling in history, specifically in Greek and Roman literature.

This is THE source for answering the question, "Did Greeks and Romans whistle tunes?" A.V. van Stekelenburg takes us through different kinds of whistling and presents evidence for the existence or non-existence of musical whistling, catcalls, the wolf-whistle, semaphoric or signal whistling, etc.

Let's start with a simple history of whistling and of related topics in the study of the art of whistling. This is a paper written by the psychiatrist Peter F. Ostwald. There are few writers who tackle the subject of whistling and this paper is one of the few.

I want to share with you my interest in whistling as an art and as an avocation through history. I am learning as I go along and I want to share that journey with you as I learn about whistling in literature, in recorded music and in many other areas. It doesn't matter if you can whistle or not. Maybe it's time to learn.
