+A template to write a score for a diatonic accordion.
+
+- There is a horizontal staff indicating if the accordion must be
+pushed (thick line) or pulled (thin line)
+
+- There is a small rhythmic staff with lyrics that describes the bass
+buttons to press. The bar lines are made from gridlines
+
+- The tabulator staff for diatonic accordions shows the geographic
+position of the buttons and not (as for every other instrument) the
+pitch of the notes; the keys on the melody-side of the accordion are
+placed in three columns and about 12 rows
+
+
+In the tabulator staff notation the outermost column is described with
+notes between lines, the innermost column is described with notes
+between lines and a cross as accidental, and the middle column is
+described with notes on a line, whereby the row in the middle is
+represented on the middle line in the staff.
+
+
+Some words to transpose piano notes to the diatonic accordion:
+
+
+1. Every diatonic accordion is built for some keys only (for example,
+for the keys of C major and F major), so it is important to transpose a
+piano melody to match one of these keys. Transpose the source code, not
+only the output because this code is required later on to translate it
+once more to the tabulator staff. This can be done with the command
+@code{displayLilyMusic}.
+
+
+2. You have to alternate the push- and pull-direction of the accordion
+regularly. If the player has a too long part to pull the accordion gets
+broken. On the other hand, some harmonies are only available in one
+direction. Considering this, decide which parts of the melody are the
+push-parts and which the pull-parts.
+
+
+3. For each pull- or push-part translate the piano notes to the
+according tabulature representation.
+
+
+This snippet comes with a useful optional macro for the jEdit text
+editor.

+ %How to fast write the push-lines:
+ % 1. write repeatedly 'c c c c c c c c |' for the whole length of the song
+ % 2. uncomment the line \NoNoteHead
+ % 3. compile
+ % 4. Mark the positions on which push/pull changes.
+ % In the score-picture click on the position the push- or pull-part starts
+ % (on the noteHead, the cursor will change to a hand-icon).
+ % The cursor in the source code will jump just at this position.
+ % a) If a push-part starts there, replace the 'c' by an 'e['
+ % b) If a pull-part starts there, replace the 'c' by an 's'
+ % 5. Switch into 'overwrite-mode' by pressing the 'ins' key.
+ % 6. For the pull-parts overwrite the 'c' with 's'
+ % 7. For every push-part replace the last 'c' with 'e]'
+ % 8. Switch into 'insert-mode' again
+ % 9. At last it should look lik e.g. (s s e[ c | c c c c c c c c | c c c c c c e] s s)
+ % 10. re-enable the line \NoNoteHead
