## Music and Numbers: Trumpet and Organ Videos

Dr. Carol Reynold’s excellent presentation on December 4th featured several videos illustrating her talk.  We’ll begin posting those videos here beginning with a man playing a trumpet relying entirely on the physics of his mouth:

And here was the fascinating video of a man explaining how he built his own pipe organ.

## Math, Music and Acoustics

We hope you are all looking forward to our December 4th lecture by Dr. Carol Reynolds on Music and Numbers.  In case there are any doubts about the many rich connections between mathematics and music, Dr. Reynolds sent some excellent resources on Acoustics.

## Acoustics and Vibration Animations

Dr. Dan Russell, a professor of applied physics, has used Mathematica software to visualize and explain complex acoustical phenomenon.  Here for example is his explanation for one mode of a drum head vibrating:

The (0,3) mode, shown at right (MPEG movie ) has three circular nodes, but no diameter nodes. The frequency of the (0,3) mode is 3.598 times the frequency of the (0,1) mode. Like the (0,1) and (0,2) modes, the (0,3) mode is excited when the membrane is struck at the center. The sound radiation characteristics of the (0,3) mode rather complicated. This mode is excited when the membrane is struck at the center, and it dies away fairly quickly. As a result, it contributes to the “thump” sound when a drum is hit at the center, but does not contribute much to the musical pitch of a drum when hit off center.

These online multimedia lectures provide a great introduction to the physics of sound.  Topics include oscillations, travelling waves, the Doppler effect, interference and standing waves.  They also have articles specific to many of the instruments our students play:

## December 4 – Music and Numbers

On December 4th we will have a very special holiday lecture from Dr. Carol Reynolds.  Her talk will explore the intersections between mathematics and music:

Music and numbers?  How interrelated are they?  Everyone knows about rhythm and counting 1-2-3-4.  And you probably know that math figures into music theory, (primarily the study of harmony and form).  But what about acoustics, the science of sound?  And music notation (the historical systems for writing music down on paper)?  How about the composition itself?  Could numbers be a factor?

Using sound and visual images, Dr. Reynolds will travel through the many ways that numbers, math, and symbols occur in music, both in today’s practice, and in musical systems of the past.

For more than 20 years, Dr. Carol Reynolds was Associate Professor of Music History at the Meadows School of the Arts, Southern Methodist University in Dallas, Texas.

Carol also is a uniquely talented and much sought-after speaker for arts venues and general audiences. Never dull or superficial, Carol brings to her audiences a unique mix of humor, substance, and skilled piano performance to make the arts more accessible and meaningful to all.

Carol has led arts tours to Russia, Austria, Germany, San Francisco, and Broadway on behalf of several arts organizations. Her enthusiasm and boundless energy give tour participants an unforgettable experience.

She makes her home on a farm near Bowie, Texas, where, with her husband and teenage daughter, she raises La Mancha goats and soaks up the rich cultural heritage of rural America. She maintains a second residence in Weimar, Germany — the home of Goethe, Schiller, Bach, and Liszt, and the focal point of much of Europe’s artistic heritage.
