\section{ Notes and Scales in Hindustani Music}

The basic alphabets of the Hindustani music would be the following.

\begin{itemize}
\item Mandra Saptak - \d{S} \d{\b{R}} \d{R} \d{\b{G}} \d{G} \d{M} \d{\'{M}} \d{P} \d{\b{D}} \d{D}  \d{\b{N}} \d{N}
\item Madhya Saptak - S \b{R} R \b{G} G M \'{M} P \b{D} D \b{N} N
\item Tara Saptak - \.{S} \b{\.{R}} \.{R} \b{\.{G}} \.{G} \.{M}  \.{\'{M}} \.{P} \b{\.{D}} \.{D} \b{\.{N}} \.{N}
\end{itemize}

Every composition will be written using the above notes.
We need  a way for the user  to be able  to write each of these notes  fast.
We can follow  the  following notation to write  the notes in Madhya  Saptak(middle  octave)
\begin{itemize}
	\item S - Shudha Sa -  S
	\item r - Komal Re - \b{R}
	\item R - Shudha Re - R
	\item g - Komal Ga - \b{G}
	\item G - Shudha Ga - G
	\item m - Shudha M - M
	\item M - Teevra M - \'{M}
	\item P - Shudha P - P
	\item d - Komal Da - \b{D}
	\item D - Shudha Da - D
	\item n - Komal Ni - \b{N}
	\item N - Shudha Ni - N	
\end{itemize}

For the Mandra Saptak  we can use S1, r1, R1,  g1, G1, m1, M1, P1, d1, D1, n1, N1

For the Tara Saptak we can use  S2, r2, R2,  g2, G2, m2, M2, P2, d2, D2, n2, N2

So something  written as S R G m P D N S2 should be rendered as
S R G M P D N \.{S}

\section{Representing the notes per beat}

\begin{itemize}
\item $\dfrac{1}{2} beat\matra{SR}$
\item $\dfrac{1}{4} beat\matra{SRGM}$
\item One Beat - SR
\item $1\dfrac{1}{2} beat - S\matra{-R  }$ 
\end{itemize}

\section{Ornamentation}
\begin{itemize}
\item Meend - \meend{SR}
\item Kan - $^{D}P$
\item Khatka (P) - \matra{PDMP}
\end{itemize}
