四月，在阳光下聆听——巴萨诺瓦

　　
　　Lush orchestral accompaniment is often associated with bossa nova's North American image as "elevator" or "lounge" music. While it is present, perhaps excessively, in much of Jobim's own recordings, it is rarely heard elsewhere.
　　
　　Structure 音乐结构
　　Bossa nova is at its core a rhythm, and one based on the samba. Samba is in turn partially derived from European march music, and emphasis on the first beat carries through to bossa nova (to the degree that it is often notated in 2/4 time). When played on the guitar, the thumb plays the bass notes on 1 and 3, while the fingers pluck the chords in unison on 1 and 2, delayed on 3. Overall, the rhythm has a swaying rather than swinging (as in jazz) feel. As bossa nova composer Carlos Lyra describes it in his song "Influência do Jazz", the samba rhythm moves "side to side" while jazz moves "front to back".
　　
　　In terms of lyrical themes and length of songs (typically 2-4 minutes), bossa nova is very much a "popular music" style. However, the typical structure differs slightly from European and North American rock-based music's standard format of two verses followed by a bridge, and a closing verse; bossa nova songs usually have no more than two lyrical verses, and almost never a bridge. Some of João Gilberto's earliest recordings were less than 2 minutes long, and some had a single lyrical verse which is simply repeated.
　　
　　Origin of the term "bossa nova"
　　"bossa nova"一词的由来
　　Bossa Nova of course means "New Bossa", but according to Ruy Castro, author of Bossa Nova: The Story of the Brazilian Music That Seduced the World, the word "bossa" itself was "far from new" at the time of "Chega De Saudade," and had "been used by musicians since the days of yore to define someone who played or sang differently....In 1932, Noel Rosa used the word in a samba...which went O samba, a prontidão e outras bossas/São nossas coisas, são coisas nossas (Samba, empty pockets and other bossas/Are our specialities." Castro writes that an editor in Brazil, Moysés Fuks, in 1958 wrote a program for a show featuring Roberto Menescal and other performers, and billed it as a "bossa nova evening" Castro writes, "The origin of the expression has never been completely clarified."
