While most musical instruments are man-made, one—the voice—is a natural part of the human body. Because the voice and the person using it are inseparable, singing is a particularly personal form of expression. Many vocalists, even professionals, experience a sense of vulnerability related to the use of their bodies as expressive, emotional instruments. Vocalists who take expressive risks, despite these feelings, are often the musicians we most closely relate to on a human level; John Lennon, Amy Winehouse, and Aretha Franklin are among that special group. Such singers are sometimes described as authentic, because they are perceived as revealing themselves honestly, or as some might say, “from the heart.”
Singers were among the first musicians to benefit from the emerging recording technologies of the early 20th century. While previously a loud voice was a survival skill—singers depended primarily on volume to be heard—artists such as Bing Crosby and Frank Sinatra embraced the microphone, singing softly and with a dynamic range that would have been lost before the microphone’s invention. To many who were accustomed to the “shouters” of the past, the softer tones of singers such as Crosby and Sinatra signaled a dramatic shift.
With the heightened sense of intimacy made possible by microphones also came increased scrutiny of vocal performances. Projected over the musical accompaniment, singers were heard with increased clarity, and many also felt more exposed and vulnerable. As students discover while completing the vocal activity in this lesson, by nature the sound of one’s own recorded voice often sounds alien, not quite right. We hear our own recorded voices in a way that is different from how we hear other’s recorded voices. Many singers, even professional musicians, report such a feeling. For instance, in Soundbreaking Episode Three, The Who’s Roger Daltry reports that he and most of the vocalists he knows dislike hearing recordings of their own voices.
As recording technology improved, many singers embraced studio techniques that enabled them to manipulate their recorded vocals with effects such as reverb, which creates a sense of physical space around the voice, or even push toward a perfect performance by splicing the best moments of several takes. Some singers, such as The Beatles’ John Lennon, employed double-tracking, a process of thickening a vocal performance by recording a second, nearly identical version atop the original.
Since the dawn of the digital recording era in the early 1990s, the possibilities for vocal manipulation have only increased, with software such as Antares Audio Technologies’ Auto-Tune encouraging musicians, producers and engineers to aspire to perfect performances. Auto-Tune pushes and pulls vocalists’ pitches toward selected notes, correcting the pitch. Most recordings are in some way corrected, but some critics argue that pitch correcting technologies risk removing the human element from recorded vocals. The very vulnerability that listeners often connect with can be compromised.
There are many who believe that less is more when it comes to using technology. This is the heart of the debate around recording vocals in music: how much manipulation is too much? If recording engineers and producers can use computers and software to digitally alter a vocal track, what happens to the original voice, and what role does talent play? To many, there is a fine line between the perfection that can be achieved with technology and the experience of authenticity in a recorded vocal performance. This lesson explores the ways in which music technology can enhance a singer’s performance. It also considers the listener’s interest in hearing the authenticity of a vocal performance. Either way, the heart of most popular music is the same, important center: the human voice.
How did the development of microphones in the 20th century change the way people make and listen to music?
Upon completion of this lesson, students will:
- Know (knowledge):
- That the human voice, like the guitar or keyboard, is an instrument
- About the different ways vocal tracks can be manipulated during the recording process
- How music technology has changed the way voices are experienced on recordings
- About the different ways singers can be musically expressive with and without recording technology and the debates around technological manipulation
- How recording the human voice changed in the digital era, and how that change reflects contemporary life
- Be able to (skills):
- Evaluate the effects of technology on history and culture
- Analyze and compare contrasting viewpoints
- Interpret critical readings
- Apply knowledge of specific concepts and ideas to broader historical situations

Ask your students:
- Do you think the human voice is an instrument? Why or why not?
- In what ways do you think the human voice is different than other instruments? (Students might answer that the voice is part of your body and not an object, or that it’s inside your body and therefore you can’t see it like other instruments. They may also mention that you use your voice for activities not related to music-making.)
- Show Clip 1, Soundbreaking - Annie Lennox on Vulnerability. Ask your students:
- Why do you think Lennox considers the voice a vulnerable instrument, or feels that singing is a vulnerable act? (Students should remember that Annie Lennox describes being judged by people.)
- Have you ever been judged for your voice? Can you think of situations where you or others have judged someone’s singing voice? (Students might mention American Idol or other “contest” TV shows as well as singing in groups at social events, such as singing “Happy Birthday.”)
- Authentic: genuine, sincere, representing one’s true nature or beliefs
- Authenticity: the quality of being authentic, genuineness, trustworthiness
- Ask your students:
- What do you think Annie Lennox might have meant in the last clip when she described an “authentic vocal performance”?
- In what ways do you think singing can be thought of as a “personal matter”?
- How do you think singing is different from other instruments?
- Record yourself speaking the first stanza of the Pledge of Allegiance. Then listen back to the recording. Then have your partner do the same.
- Record yourself singing “Happy Birthday” and then have listen to the recording. Have your partner do the same.
- When you heard the recording of your speaking voice did it sound like you expected it to? How did the sound of your voice on the recording contrast with the way you hear your voice in your head as you speak?
- Did the recording of your partner sound different than your partner’s voice sounds to you otherwise? How and why?
- Did you find it hard to sing in front of your partner? If so, why?
- Do you like the way your voice sounds on the recording of you singing? Why or why not?
- Did anyone feel self-conscious or vulnerable when talking on the recording? How about when singing? What do you think is different in these two situations?
- Having done this exercise, in what ways might you now explain singing as a “personal matter” now?
- What happens when you turn on reverb? How would you describe the effect? (Students may suggest that the voice sounds bigger or more distant. Reverb creates a sense of physical space around the voice.)
- Why do you think a singer would choose to add reverb to his or her voice?
- What do you think is happening when you turn on double-track? (Students may say they hear two singers. Double-tracking is adding a second layer of the same part.)
- Why do you think a vocalist would want to employ a double-track of his or her voice?
- In what ways might double-tracking help a person who felt some sense of vulnerability about his or her voice? (Students may suggest that it thickens the sound or that the second track makes it seem less like a single person singing.)
- What are some of the different approaches to making a vocal recording explained in this clip? What are the main differences between the approaches described by Suzanne Vega and Smokey Robinson? (Students should remember Suzanne Vega’s explanation of the splicing of different takes as well as Smokey Robinson describing his preference for performing a “concert in the studio.”)
- In what ways do you think splicing vocal takes to make what Vega calls an “ideal” vocal performance might help a singer who feels vulnerable in the studio? (Students might mention that splicing allows a singer to pick only the moments they like in each successive performance.)
- The technique of“splicing caused some to question the authenticity of vocal performances that used it. Looking again at the definition of authentic from earlier in this lesson, in what ways might this studio technique cause some to feel this way? (Encourage your students to discuss how some might have felt that spliced vocal takes were not “genuine” or “true” and thus, not authentic.)
- Have you ever heard of Auto-Tune before this class? Are there any artists you know of that use it in an audible way?
- How would you describe the Vocoder vocal effect used by Zapp & Roger at the beginning of this clip? Why do you think a vocalist would choose to use this effect? (Students may suggest that the voice is robotic, and that it provides a different layer of sound or perhaps even makes the music sound futuristic.)
- What is the South Park scene within this clip suggesting about Auto-Tune and music technology in general?
- Thinking back to our earlier discussion of authenticity, do you think the South Park clip is making a point about authenticity?
Distribute Handout 2: New York Magazine Excerpt and read it out loud as a class. Discuss with your students:
- Why do you think the author states that an unsullied recording is the “Sasquatch” of music? What does this analogy imply? Do you think he believes there is such a thing as a completely natural recording?
- Thinking about the technologies we’ve discussed throughout this lesson, in what ways do you think the analogy of “applying make-up” works or does not work for the functions they perform in recording vocals? (Students may agree or disagree. Perhaps some effects are like make-up and others are akin to plastic surgery?).
- If students have access to computers or iPads, have them go to TwistedWave Online, a free web site that allows people to experiment with recording a vocal track and editing it with various effects. (The site can be used without logging in, but students can’t save their end product unless they create a login.)
- Have students each choose one of these five activities and create a group with which they can meet after class: Writers, Visual Artists, Athletes, Dancers, and Musicians. Assign one student from each group to be the note-taker for the group. Ask students:
- How do you think expressing emotion while performing your activity might affect its outcome?
- How do you think your group might feel vulnerable while performing your activity?
- Do you think it’s important to express emotion and allow yourself to be vulnerable while performing your activity?
- Allow students some discussion time before asking each note-taker to present their group’s discussion to the rest of the class.
- Step 1: Before doing any research, write down three things you think of as being “authentic.”
- Step 2: Define “authentic” in several ways.
- Step 3: Return to the list you made in Step 1. Has your feeling about the “authenticity” of these things changed at all?
