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 3 semitones above the root and 6 semitones above the root, invariant of octave. This means that notes in a major chord must be 3 and 6 semitones above the root modulus 12. See figure ~\ref{fig:qualitytable} figure~\ref{fig:qualitytable}  for a sample of commonly named chord qualities and the associated intervals. \begin{figure}[h!]  \begin{center} 

\end{center}  \end{figure}  A chord with only 3 notes in which successive intervals are in the same octave is called a \textit{triad}. A C major triad is demonstrated in figure ~\ref{fig:cmajorchord1}. figure~\ref{fig:cmajorchord1}.  % The octave of these successive notes can be incremented or decremented freely, and the chord is still considered to have a \textit{major} quality. See figure for a C major chord in root position.  % Chords feature a \textit{root note} which is the note around which the \textit{quality} is based.
