I would say no, as perfect pitch requires a fundamental ability that most people simply don’t have. I have extraordinary relative pitch. I can pick out intervals and sequences of notes with precision that can split a hair. I can have music in my head for hours and give you the name of a note, so sometimes it even seems like perfect pitch. Play a note to me out of the blue and I am dead in the water. Perfect pitch is just a different ability. The combination of perfect pitch and synesthesia would be interesting.
But that’s my point, my friend could distinguish notes with complete accuracy even before he had any formal musical training - he just didn’t know the names until he was taught them.
That is extremely unusual. Most people with perfect pitch began music very young. It is also the best example that this is an unlearned talent that is unrealated to synesthesia. This freind of yours is fundamentally gifted (or cursed as some have described it.) to distinguish pitches out of the blue. It is a physical talent that is quantifiable. It is a very different phenomenon from associating taste with shape or whatever.
My synaesthetic sensations are very definite (as a small child I remember pestering my mother “but what color is Tuesday?” because that’s the only day of the week I don’t see something for). But they are very restricted in range. Numbers, days of the week (except Tuesday), and certain vowel sounds all have colors: either grey, black or a dull orange.
Heh. I’m a color-blind synaesthete.
Isn’t it funny that there are exceptions? 9, O and Q are virtually colorless to me.
It’s hard for me to grasp the concept of not having synaesthesia. When I listen to a song, for example, each element of the music has a specific color, shape and texture. What do normal people “see” when they listen to music? If they close their eyes, do they just see nothingness?
Oh, cool, a synaesthete thread!
I’m only mildly synaesthetic, and while I (thank the gods) no longer get migraines, it used to be the case that it would kick into major overdrive during a migraine. It would overwhelm me massively to the point of hallucinating and taking over my language. You’d know I’d be in bad shape if I started referring to the sink ribbons (running water).
I’m also an artist, which produces some interesting results at times, but honestly, I don’t know how I’d handle not being this way. It just makes it so much better. Words are tangible, sounds are tangible, foods set off little displays of fireworks in my head (which is probably why if I don’t like the way something tastes, I wind up gagging on it and being unable to eat without actually puking)
This is probably the largest gathering of synaesthetes I’ve seen. Awesome. 
That’s an interesting point and one I’ve tried many times to convey to the people who ask me about my synaesthesia.
Imagine for a moment the colour red. Now imagine that I have newly visited this planet and have no concept of ‘red’. Now try to explain to me what red is. And to make things as difficult as it is for a synaesthete to describe their sensory experience you may not describe it with reference to anything, for example ‘It’s the colour of this apple’ isn’t allowed. Just try that for a moment.
Difficult isn’t it? People could come up with things like fiery or bold but red isn’t actually any of these things. It’s not hot. It’s not thick and block and nor is it brave. It is INCREDIBLY difficult to describe sensory experience. How does a non-synaesthete describe music or hearing? How does anyone?
