Emily F. OB 15: Understanding the mechanics of sound can aid in the good production of vocal sound. For example, "If the notes are well produced, high tones need no amplification." This is important to know! If the frequency (pitch) is high, it will have more intensity (loudness) and requires less energy force than a lower pitch to get the same dB. So, singers needn't push or feel like they're singing as loud on higher notes.
Key concept: "...the science of sound can enhance and facilitate the process [of vocal production]."
Key terms: sound, frequency, pitch, intensity, loudness, wave form, quality, time, hertz, condensations, rarifications, natural level, habitual level, decibels, Bernoulli effect, Venturi effect, fundamental frequency, overtones, sine wave, resonance
Making connections: So in church choir yesterday I was singing soprano and had to sustain a G for a while. I was trying to use the best, easiest technique I could, so I was trying to let my voice just float. I also thought about how higher pitches "carry" easier, so that took the pressure off of me having to sing that G so loudly. I'm the only soprano in my ward choir who can sing these notes, so the pressure is on me to carry the group. It's nice to know that I don't have to work so hard for those high notes.
