In bluegrass music, a banjo roll or roll is an accompaniment pattern played by the banjo that uses a repeating eighth-note arpeggio – a broken chord – that by subdividing the beat 'keeps time'. "Each () roll pattern is a ''right hand'' fingering pattern, consisting of eight (eighth) notes, which can be played while holding ''any'' chord position with the left hand."〔 "When used as back-up, the same pattern can be repeated over and over throughout an entire song, (...(chord changes ) as required), or the roll patterns can be combined with one another and with (licks )... The roll patterns can also be used to embellish the vamping style of back-up, especially when the chords are played high... These roll patterns can be used as back-up for any song played at any tempo."〔 The banjo is commonly played in open tunings, such as open G (as are all of the examples): G'DGBD', allowing rolls to be practiced on all open strings (without fretting). Rolls are a distinguishing characteristic of Scruggs style banjo playing, with older styles being more melodic.〔Cantwell, Robert (2002). ''Bluegrass Breakdown: The Making of the Old Southern Sound'', p.100. ISBN 0-252-07117-4.〕 The older style of banjo playing has been described as "in 'phrases,'" and with, "really no connective tissue between four notes and next four notes...sorta like a gallop. Snuffy () was a little like that...old sounding, choppy...".〔Tom Warlick, Lucy Warlick, and Robert Inman (2007). ''The WBT Briarhoppers'', p.150. ISBN 0-7864-3144-X.〕 Banjo rolls serve a variety of functions within an ensemble: Banjo rolls, the basis of the Scruggs style "pioneered by Earl Scruggs",〔 "were undoubtedly based on" classic or fingerpicking banjo, itself based upon and simultaneous with (mid-1860s) parlor-style guitar.〔Trischka, Tony (1992). ''Banjo Songbook'', p.20. ISBN 0-8256-0197-5.〕 "The word roll has different meanings for different kinds of musicians. To guitar players, a roll is a broken chord; to bluegrass-banjo players..."〔Perlman, Ken (1989). ''Clawhammer Style Banjo'', p.163. ISBN 0-931759-33-1.〕 Rolls may start at any point in the pattern or, in other words, on any finger.〔Davis (2002), p.56〕 ==See also== *"Shave and a Haircut" *G run *Chop chord 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「banjo roll」の詳細全文を読む スポンサード リンク
