Hello I have a quiet simple question. I would like to know which is the traditional position of the Ritardando sign.
Dorico is putting it above the Lines, but I heard a few Times that the traditional position is below the System.
can somebody have realiable hin. about that?
Thanx
Elaine Gould writes: “It is standard practice to place each [tempo alteration] marking a small distance above all other information on the uppermost stave.” (Behind Bars, p. 184). However, there are always exceptions to this rule.
Context is everything. What are you writing for? “Some traditions” put tempo marks above the system (i.e. above a group of staves); but there are “other traditions”, such as choral music, where it’s equally common to write tempo changes on each staff, because singers only look at their own line. 
There is also a recent lengthy (and heated) debate about putting tempo alterations between the staves of a piano.
Thank you both. i am writing for a twenty peliece Orchestra in very different instrumentations
So there is Balkan Polka mixed with Neo Brock etc
and a drummer ask for putting the Ritardando below the system
so if both is possible I will keep it as doricles suggests it
Thankj you
