The following instructions show the various pipes used in the Canadian Navy. The numbers at the top of each figure represents seconds of time. The nature, continuity and tone of the notes are indicated by the various lines, and the degree of their slope indicates the speed of ascent or descent of the notes.
The still is used to call all hands to attention as a mark of respect, or to order silence on any occasion. The still is also used to announce the arrival onboard of a senior Officer. The pipe is an order in itself and does not require any verbal addition. The still is a high note held for 8 seconds. If done properly, it should end very abruptly.
The carry on is used to negate the still. The pipe is an order in itself and does not require any verbal addition.
The general call precedes any broadcast order; it draws attention to the order. The general call is used when passing out-of-routine orders or information of general interest.
Officer of the Day Call
The Officer of the Day call is used to attract the attention of the Officer of the Day to contact the gangway. The pipe is an order in itself and does not require verbal addition. The pipe consists of 4 high "pips".
Pipe the Side
When a Commanding Officer of an HMC ship arrives onboard he/she is entitled to this pipe. To be done properly it should be 12 seconds long with very smooth transitions. To accomplish this, the sailor must take a very long deep breath prior to beginning; failure to do so will cause the pipe to be abruptly cut short. The side is also piped for Royalty, teh Accused when entering a Court Martial and for the Officer of the Guard (When the Guard is formed up).
Hands to Dinner
The hands to dinner pipe is made at 1200 when the Ship's Company secures and commences the mid-day meal, referred to as dinner. It is never made for any other meal-time. The pipe is an order in itself and does not require any verbal addition. This pipe is very long and any is the pride of any sailor that can do it absolutely properly, and the disgrace of any sailor that does not.
The pipe down is made at 2230 or at any other time specified by the routine daily orders, when the Ship's Company retire for the evening and the silent hours period commences. The pipe is an order in itself and does not require any verbal addition. When this pipe is made during the middle of the day, it means that the ship is adopting a "Sunday Routine for the remainder of the day.
