They are all supposed to have frets. Sometimes they fall out if the guitar is handled rough.
Not all guitars have frets, however, it is probably best to learn using frets.
Guitars with fanned frets have frets that are angled, allowing for longer scale lengths on lower strings and shorter scale lengths on higher strings. This can improve intonation and playability, especially for extended range guitars. Normal frets have a consistent scale length across all strings.
Guitars with super jumbo frets offer easier bending and vibrato techniques, improved intonation, and increased sustain compared to guitars with regular-sized frets.
Guitars with extra jumbo frets offer easier bending and vibrato techniques, improved intonation, and increased sustain compared to guitars with standard frets.
Fanned frets are used in some guitars to improve intonation and playability across all strings by accommodating different scale lengths for each string.
Depends entirely on the size of the guitar, what type of guitar, manufacturer ect. Most guitars have 22 frets on them, but some have up to 24. Some smaller-sized acoustics have as little as 18 frets on them, but all full sized guitars will have at least 22. all normal guitars have 22 or 24, but some have 21 or 25, and recently, ibanez made a guitar with 30 frets
Violas do not have frets. Nor do violins or cellos. Frets are found on stringed instruments such as guitars.
24..and some bass-guitars with 25 frets.
Guitars with fanned frets offer improved intonation, better string tension balance, and enhanced playability across the fretboard compared to traditional fretted guitars.
no lots of guitars do
If I understand correctly, the pardas on a sitar correspond to the frets on a guitar. Different guitars will have a different number of frets. Some electric guitars have a full two-octave neck, which means 24 frets. More common is for guitars to have 20 or 21.
That depends on the type of guitar you have. I work with Guitars everyday so I see guitars with 12 frets, 14 frets, 17 frets, 21 frets, 23 frets and occasionally I find 24 fret guitars (with the double octave of the open string) the most frets I have seen was a 29 fret electric guitar. The guitar was custom built though. Most commonly, you will find acoustics with probably 14 to 17 frets and electric guitars with 17 to 21 frets.
