AABA form: a song form that features two statements of the verse (A A), a bridge (B), and a return to the verse (A). The sections may be repeated as a reprise or partial reprise. Sometimes the B section is called the “middle 8.” accent: a musical event that receives emphasis through intensity (dynamics), duration, density (thicker texture), or pitch. accompaniment : the part of the musical texture that supports the main melody. ambience : the acoustical character of an enclosed space; in record production, it usually refers to the effect produced by reverberation. amplifier : a device that increases the power, and hence the amplitude, of an audio signal. arpeggio : the articulation of the individual notes of a triad or chord . attack : the initial onset of a sound. backbeat : a percussive accent on the second and fourth beats of the bar, which traditionally are considered the weaker beats in the meter. bar (measure): the unit of measurement in time that forms the basis of meter; each bar is broken down into beats. For example, in 4 beats per bar, the time is parsed as follows: Bars: 1 2 Beats: 1 2 3 4 1 2 3 4 beat : a regular rhythmic pulse in music. The beats are organized into bars (measures). blue notes : a variable lowering of the third, seventh, or sometimes fifth degrees of the major scale. blues : an important style in popular music that is based on certain patterns: the 12- bar blues pattern, string bends and vocal inflections to create “blue” notes. boogie rhythm : a repetitive pattern that is shuffled to create a driving groove; usually a “walking” melodic pattern in the bass. bridge : a section in a song that provides contrast to other more predominant sections, such as the verse or chorus. cadence : a melodic or harmonic event that signals the end of a musical phrase or section. A cadence can create a closed effect (a resolution of the melodic, harmonic and rhythmic material), or a cadence can create an open effect, suggesting that more is to come. call and response: an exchange between two instruments such that a gesture in an instrument or voice is immediately answered or repeated by other instruments or vocals. chord : a combination of three or more notes played at the same time to create a harmony. chord progression: a series of chords.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
