question: What voice type does Sonny Bono's collaborator on the album Chér have?
answer: contralto
context: Title: Voice type
  Passage: A voice type is a particular human singing voice identified as having certain qualities or characteristics of vocal range, vocal weight, tessitura, vocal timbre, and vocal transition points ("passaggio"), such as breaks and lifts within the voice.  Other considerations are physical characteristics, speech level, scientific testing, and vocal register.  A singer's voice type is identified by a process known as voice classification, by which the human voice is evaluated and thereby designated into a particular voice type.  The discipline of voice classification developed within European classical music and is not generally applicable to other forms of singing.  Voice classification is often used within opera to associate possible roles with potential voices.  Several different voice classification systems are available to identify voice types, including the German "Fach" system and the choral music system among many others; no system is universally applied or accepted.

  Passage: "Bang Bang (My Baby Shot Me Down)" is the second single by American singer-actress Cher from her second album, "The Sonny Side of Chér".  Written by her then-husband Sonny Bono and released in 1966, the song reached No. 3 in the UK Singles Chart and No. 2 on the "Billboard" Hot 100 for a single week (behind "(You're My) Soul and Inspiration" by The Righteous Brothers), eventually becoming one of Cher's biggest-selling singles of the 1960s.
  Title: Laugh at Me
  Passage: "Laugh at Me" was Sonny Bono's only hit song as a solo artist under the name Sonny.  The song was released in 1965 and reached #1 in Canada on the "RPM" national singles chart (to be knocked off the top spot the following week his own Sonny & Cher single, "Baby Don't Go").  It peaked at #10 in the U.S. and at #9 in the United Kingdom.  Thus, Sonny hit the Top 10 in all three countries as a solo artist before Cher.  The song was written and produced by Bono after he was refused entrance to Montoni's Restaurant in Hollywood because of his "hippie attire".  The song begins with Sonny saying, "I never thought I'd cut a record by myself but I got somethin' I wanna say.  I want to say it for Cher and I hope I say it for a lot of people."
