+  \frametitle{Welcome to Bogenherr}
+  \begin{itemize}
+  \item Been playing the viola for 47 years.
+  \item Picked up the violin and viola d'amore later on.
+  \item 100\% classical musician. Not an improvisor. Focus is on
+    interpretation.
+  \item Channel mission: just a place to record my musical
+    journey:
+    \begin{itemize}
+    \item Performing
+    \item Pedagogy
+      \begin{itemize}
+      \item As student
+      \item As teacher
+      \end{itemize}
+    \end{itemize}
+  \item After 47 years I have gathered a lot of knowledge that others
+    might find useful.
+  \end{itemize}

+  \frametitle{Warmup Video Series}
+  \begin{itemize}
+  \item Making a series of videos documenting my viola warmup
+    routine.
+  \item Five core drills which I do in this specific order:
+    \begin{itemize}
+    \item Trills
+    \item Short fast bow strokes
+    \item One-string ``modal'' scales
+    \item Arrepggios
+    \item Kreutzer \#24
+    \end{itemize}
+  \item All drills focus on three areas:
+    \begin{itemize}
+    \item Left hand
+    \item Right hand
+    \item Posture and alignment
+    \end{itemize}
+  \item Goals:
+    \begin{itemize}
+    \item Total relaxation and efficiency.
+    \item An easy and effortless technique with no pain and injury.
+    \item A highly capable technique that supports the hardest passages.
+    \end{itemize}
+  \item One video per drill.
+  \item This is the first video in the series which will cover Trills.
+  \end{itemize}

+  \frametitle{Trill Warmup}
+  \begin{itemize}
+  \item (Play it on the A string to provide an example.)
+  \end{itemize}
+\end{frame}

+\begin{frame}
+  \frametitle{Core Checklist: Left Hand}
+  \begin{itemize}
+  \item Three contact points:
+    \begin{itemize}
+    \item Thumb
+    \item Base of index finger
+    \item Tips of fingers
+    \end{itemize}
+  \item Swing elbow to the correct angle for the string. Hand is
+    oriented such that the fingers naturally fall right onto the
+    correct spots.
+  \item All finger motion from the base knuckles.
+  \item Finger keeps its curved shape. No other joints move. Extra
+    attention to 4th finger.
+  \item Barely touch the strings. No extra force. Harmonics are OK,
+    even encouraged.
+  \item No tension in the hand, especially across the back of the hand
+    between the wrist and base knuckles. Floppy.
+  \end{itemize}
+\end{frame}
+
+\begin{frame}
+  \frametitle{Core Checklist: Right Hand}
+  \begin{itemize}
+  \item Tiny inputs and complete relaxation.
+  \item No extra weight on the bow stick. Glide across the surface
+    of the strings. 
+  \item Contact points:
+    \begin{itemize}
+    \item Thumb tip against the stick.
+    \item Outside of thumb against the bow hair.
+    \item End joints of the first three fingers very lightly wrapped
+      around the top of the stick.
+    \item Thumb is directly opposite the crack between the 2nd and 3rd
+      fingers.
+    \item The outside of the thumb tip and the very tip of the second
+      finger should be in contact with the bow hair at all times.
+    \item The 4th finger curves relaxedly and sits on top of the
+      stick.
+    \item The thumb has a healthy amount of curve. The curve hangs
+      nearly straight down toward vertical.
+    \end{itemize}
+  \item Up-bow and down-bow motions are entirely linear. No extraenous
+    movement in any other plane. Feel the bow stick tugging against
+    the skin of the fingers, and also the thumb and middle finger
+    guiding the ribbon of bow hair.
+  \end{itemize}
+\end{frame}
+
+\begin{frame}
+  \frametitle{Core Checklist: Posture}
+  \begin{itemize}
+  \item Forces align vertically.
+  \item Button directly into neck.
+  \item Find instrument angle where the jawbone lines up with the
+    front edge of the chinrest.
+  \item Instrument held up by left hand (base of index finger and
+    thumb). No clutching with the head and shoulder.
+  \item Instrument should rest securely on the table with no help from
+    the head. No sloping angles. Stand straight with a proud chest and
+    noble neck.
+  \item Do not let the head tilt to the right. Lean slightly to the
+    left if anything, but vertical is best. Lead with your chest like
+    a ballerina.
+  \end{itemize}
