A chord consists of a combination of notes sounding simultaneously or close enough in succession to resemble a texture. The \textit{Harvard Dictionary of Music} defines a chord as consisting of at least three notes\cite{harvdict}. A chord perceptually describes the notes that are contained within.  Chords are commonly labeled with qualities, which describe the intervals between the pitches involved. A \textit{root note} describes the base upon which successive intervals are based. For example, given a specified root, a \textit{major} chord consists of notes 4 3  semitones above the root and 7 6  semitones above the root, invariant of octave. This means that notes in a major chord must be 4 3  and 7 6  semitones above the root modulus 12. See figure ~\ref{fig:qualitytable} for a sample of commonly named chord qualities and the associated intervals. \begin{figure}[h!]  \begin{center}
