The Accidentals in a band. Of the band's name origins, the band have stated in radio interviews that they had decided on "The Accidentals" because of the accidental note in music, which is denoted by a pitch that is not a member of the scale or mode that is specified by the most recently applied key signature, and the coincidental qualities behind its relation to their meeting each other by chance. On May 21, 2012, the Accidentals released their self-produced debut full-length album, "Tangled Red and Blue". The album features 13 tracks ranging across a spectrum of contemporary folk sounds and was
Signature of a knot represented as a "2g"-by-"2g" Seifert matrix "V", formula_7. The signature of the matrix formula_8, thought of as a symmetric bilinear form, is the signature of the knot "K". Slice knots are known to have zero signature. Knot signatures can also be defined in terms of the Alexander module of the knot complement. Let formula_9 be the universal abelian cover of the knot complement. Consider the Alexander module to be the first homology group of the universal abelian cover of the knot complement: formula_10. Given a formula_11-module formula_12, let formula_13 denote the formula_11-module whose underlying formula_15-module is formula_12 but where formula_17
