Rhythmic values are continually held for their proper duration as the tempo varies slightly. The music usually moves freely in time without a steady pulse or beat. ![]() They indicate where the measure starts and ends. The absence of bar lines indicates that time is unmeasured. Music bars are represented by vertical lines that are drawn perpendicular to the staff. A page of piano sheet music might consist of 8 'staves, but thats really 4 systems of two staves each. So, a 'system' means, a line consisting of both of those staves. Consider piano music - there are actually two staves in each 'line' of music. In music circles, it is also commonly called a measure. 'System' is a fancy musical term for 'line'. Similarly, the interval between A and B is a tone (the note A sharp/B flat is between the 2 notes): Vm. The bar, in music theory, represents a single unit of time that holds a certain number of beats played at a specific tempo. Time is divided in groups of pulses as defined in the timer signature. So, if we are playing 12 bar blues in C then the 1st bass note we play will be the note C as C major is the 1st chord in. The bassline is built on the root note of each chord. ![]() Bar lines are placed on the musical staff tor separate the divisions of time. The groove of a twelve bar blues piece is largely built on the bassline, which provides a foundation for the rhythmic feel and also the chord structure. What do the bar lines on a musical staff mean Bar Lines. For example, the interval between C and D is a tone because the note C sharp/D flat is between them: Vm. a double vertical line on a musical staff indicating the end of a piece of music or a principal section. Major, Minor, Perfect & Numbered Intervals A tone (or whole step) is an interval of 2 semitones (or half steps) added together. Some keys like B-sharp and F-flat major are seemingly absent, while others go by two names The Inefficient Keys The circle of fifths shows only the working scales. A passage between two repeats is played at least twice. Page_title=Music Theory Section 1: Music Theory A repeat bar is a barline that resembles a 'music end,' but with a dot above and below the middle staff line. ![]()
