Once a month GALA Choruses is offering tips on vocalization and singing for our chorus members. If you have tips to share or vocal questions that you would like addressed just shoot me an email. This first tip comes from veteran conductor and clinician, Dr. Stan Hill.

Tip for Singers:
Suffering from vocal fatigue after rehearsal? Research shows that an excess of sub-glottal pressure1 causes the vocal cords to do double-time. Your vocal cords are being asked to hold back an amazing amount of air pressure while controlling the air flow over the cords. But fear not, there is a great exercise that can help with the problem. The solution is to try to equalize the pressure above and below the vocal cords. This helps the air flow, helps reduce sub-glottal pressure, and can translate into more efficient phonation2.
Take a cocktail straw. Not the Big-Gulp straws but a straw with a small diameter. Placing it between the lips, sing vocal glides from the lowest notes in your range to the highest. But never let more air escape than can travel through the straw.
This exercise can reduce fatigue, develop a more efficient phonation, and allow you to sing longer, better.
Here is a YouTube demonstration by Ingo Titze, a vocal scientist and executive director of the National Center for Voice and Speech at the University of Utah in Salt Lake City.
Try it and let me know if you get satisfactory results.
1Sub-glottal pressure is the pressure below the vocal cords (glottis). It is usually measured in cubic centimeters of water (cmH2O)
2Efficient phonation or optimal phonation is the ideal balance of sub-glottal pressure and air-flow allowing for optimal vibration of the vocal folds.
