But it is true that it's often used to create a long note, something that is difficult to achieve otherwise on the instrument. Tremolo has uses besides sustain, too, such as varying volume, and even tempo. Of course, you don't want to overdo it - Picasso lingered in his "blue period" for just a couple of years - but when appropriate, nothing else will work as well instead. Tremolo is just one picking technique, one color in the sonic pallette available for the mandolin, and you would be limiting your effectiveness if you were to dismiss it from your repertoire - continuing with the analogy, like trying to paint without blue.

Tremolo is supposed to sound smooth, to a point where the individual notes almost blur into a seamless whole. If you hear "short, fast, staccato like sounds of the same note many times per beat" when you're listening to tremolo, you probably are hearing something wrong in the picking.

The relative mechanics employed to render vibrato vary widely-all of the examples you've mentioned are techniques that render vibrato they range from very slight pulsations to long glissandos, which can be less than a full portamento. Vibrato is common to most all types of instrument playing players even effect vibrato on instruments with fixed skins and string scale length and mechanical action such as drums, banjo, piano and hammered dulcimer through any manner of manipulation of keys, strings, or body of the instrument-basically any way they can. Pulsating your finger harder an softer on the string (up and down into the neck), fretted or not, would be going into and out of good intonation. Pulling or pushing a string across the neck, parallel to the string I would call string bending. I thought vibrato was moving up and down the neck along the string - as a violin does to imitate the human voice doing the slight pulsation in the frequency of the pitch, and would clearly be pointless on a fretted instrument. Well perhaps it is a terminology question. For those that hate tremolo too, what do you do? Is there some other technique that will fill the space? You know violin can just play the same note forever to fill in that space, piano has sustain. What else do I do when I come to a part in music that just screams for tremolo? You know the classics where God comes down and says, YOU HAVE TO PLAY TREMOLO HERE OR LOSE YOUR SOUL FOREVER! I guess I'm not good enough because I don't know what else to do. Here's the problem however, I cannot find a good substitute for tremolo. I guess the mandolin is the best instrument for tremolo - I guess if I had to choose my favorite then it would be mandolin. And I don't mean my own playing either, I mean on anything, anywhere, any music. No matter the tempo of the music I can just never find myself saying, wow that really fits, or that really sounds good. Whether it's flemenco guitar, acoustic guitar (i really hate it on acoustic), or even mandolin, I simply have never liked the sound of tremolo.
