Cyrus is an alto, with a "Nashville twang" in both her speech and singing voice. In "Party in the U.S.A." (2009), Cyrus's vocals feature belter refrains, while her vocals on the song "Obsessed" (2009) are noted to be "husky." Releases such as "The Climb" (2009) and "These Four Walls" (2008) featured elements of country music and showcased Cyrus's "Twangy vocals". Cyrus experimented with an electropop sound on "Fly on the Wall" (2008), a genre that Cyrus would further explore with the release of her third studio album. Can't Be Tamed (2010) was initially intended to feature dominant rock music elements prior to its completion, and Cyrus claimed after its release that it could possibly be her final pop album. The songs featured on the album spoke of Cyrus' desire to achieve freedom in both her personal life and career. Cyrus began working on Bangerz (2013) during a musical hiatus, and described the project as having a "dirty south feel" prior to its release. Critics noted the use of hip hop music and synth pop in the album. The songs on the album are chronologically placed in order to tell a story of a failed relationship, which Cyrus attributed to her relationship with Liam Hemsworth. Cyrus described Miley Cyrus & Her Dead Petz (2015) as "a little psychedelic, but still in that pop world".
