Over the years I have noticed that people have developed a habit of saying the same thing twice, often combining an articulation with a text description of said articulation. Some of these are standard conventions that I just think are a little silly, others are things I have seen people do without thinking. A lot of my approach has to do with thinking like a player and trusting them.
A wavy line up to a note means to rip into the note, that is all it can mean. Similarly, a line going down from a note can only be a fall.
A sforzando is an accent.
Marcato: marked, is performed by accenting. An accent means to give the note more emphasis than the ones around it. Save the accent articulation for when you really need one.
The tail means to let ring. The staccato is pretty universal for short, has been for a few hundred years — and don’t get me started on using an exclamation mark on the redundant ‘choke’.
This articulation can only mean snap (or Bartok) pizzicato so there is no need for the text. Also note that it is only valid for the note it is above, so no need to cancel it.
A tremolo mark in a flute (or any wood or brass) part means flutter tongue. It ‘could’ be a valve or keyed tremolo, but you would go out of your way to ask for that. Flutter is default.
The triangle note head up high means highest note, nothing else, it is universal these days.
The wavy line between two notes can only mean to gliss. What is the text for?
+ in a horn part can only mean stopped, o can only mean open. And as it only applies to the note it is above, it never carries; I don’t even put the o as common sense would say that if there is no + it is not stopped. I have never had a question from the horns about it. These are also universal for open and closed, whether you are writing a high hat part or a plunger part for the brass.
Circles above notes mean to play as harmonics in string parts at sounding pitch, unless it is harp where it sounds and octave above.
If you write the fingering for a harmonic, there can only be one outcome, why state the obvious and clutter the page?
Glockenspiel (and harp) would let the notes ring by default, no need to tell them, they have been playing since they were ten and know how their instruments work. They will play with hard mallets by default.
There is nothing wrong with clarifying. It will not do any harm, and if there is something out of the ordinary, then you should make it clear to the performer. But if the technique is obvious and covered by the standard notation, there is no need for extra specifics. Trust the players. Feel free to let me know of other examples of redundancy to add here.
