You know, listening to that youtube clip, it really does rhyme with piano - maybe with a slightly longer hold on the “a”. Listen at 4:25 after “Almost inevitably…” Are you sure you aren’t mixing up with when they say his last name “Rinaldo” that does have the long “a”?
Boy or Girl, “Lanzy”
Be the first on the planet to use it. Instant Cher, no last name needed.
See, if people want to be uneek I think it’s a 1000x better to give your kid a legitimate name from another culture (that you may admire, or maybe you just like the name) than it is to make up names that are going to sound ridiculous juxtaposed against “Dr.” or “Esq.”. Like Uma Thurman. Being named Uma is like being named Beth in Indian culture.
Cristiano is a real name from another culture. This Tiano business is just cruelty.
FWIW I tend to think that people with made up names (and honestly, this is a made up name…no one but you and maybe Cristiano himself would recognize this as a diminutive of Cristiano) face an unnecessary stigma in the working world. Who would you rather have handling your mortgage just based on name alone, D’Cargo Udwin or Robert Udwin? Shlamo Jones or Christopher Jones?
Giving your kid the name Cristiano (or even Cristian) and then using the nickname Tiano allows him the best of both worlds, or give him a first name like Henry or Robert and the middle name of Tiano. I went to school with a guy named Sale Trice Lily III (not sure of proper spelling). He was a great guy but how difficult do you think it was for him to get people to take him seriously when he applied for jobs or filled out college applications?
Only if he/she never visits Northern Ireland.
You earn a point paid in waffles. Will that be with or without the pecans?
You’re not the one who’s going to have to wear the name for his entire life; your boy is. I won’t add much because others have made very excellent points. But just because it sounds nice to you doesn’t mean it’s going to be comfortable for your son.
If you look in an American dictionary like the American Heritage, there are 2 acceptable ways to pronounce Piano. One doesn’t rhyme with Tiano, but the other does. The one that does rhyme sounds pretentious as all hell to me, but enough people say it that way it gets in the dictionary. I’m kind of sad that it’s not included in Fred and Ginger’s “Let’s Call The Whole Thing Off” since I was sure it would be. It seems like the only word that isn’t!
Out of curiousity, does anyone subscribe to the Oxford English Dictionary? It’d be interesting to see their entry for Piano, but not enough so to subscribe.
I don’t know how to copy over the pronunciation part of the entry, which copy-pastes like this: Brit. /p{shti}{sm}an{schwa}{shtu}/, U.S. /pi{sm}æno{shtu}/
I don’t know how to properly read it, but it goes something like this; I will enclose a description of each symbol in its own set of brackets:
Brit. /[lowercase p] [capitol I, written the same size a lower-case i] [apostrophe, presumably indicating stress] [lowercase a] [lowercase n] [schwa] [inverted horseshoe]/
U.S. / [lowercase p] [lowercase i] [apostrophe] [ligature (I think that’s the name for the ae-jammed-together thing)][lowercase n] [lowercase o] [inverted horseshoe] /
Do you want the definitions, etymology, and quotations as well?

I am mother to Samuel George (Sam) and Ellen Susannah (Ellen or Elle). Ok, so we could have left off the ‘h’ at the end of her middle name. Otherwise you don’t get much more traditional than those names!
My kids are Samuel Blair & Rose Miranda. We wavered a bit on using something as nontraditional as “Miranda” – it is a made-up name after all. 
Dave’s not here, man.
The OP has clearly stated that he doesn’t care whether people like the name or not.
I’m curious as to whether he cares if his child likes it or not and/or whether or not he might find it difficult and/or burdensome.
Ahem, too many and/or’s there, the board locked up and I missed the edit window.
What I meant to say in my borderline incoherent way is that I’m curious to know whether or not the OP cares if his child suffers torment or resentment over the name the OP gives him.
Yes I am worried about that. That is why I am asking people here.
People here have some wrong assumptions. One is that the name Tiano would be considered unusual in his school class. Melbourne has many cultures and many people give their kids unique names.
Also these names appeared in the top 100 names for boys in Victoria-
Taj
Hudson
Jett
Finn
Hunter
Logan
You know, I completely missed the fact that you’re posting from Australia. If Tiano wouldn’t be considered unusual where you live, and you don’t feel that your child would be bothered by endless pronunciation errors ala Roland Orzabal’s post, then I have to say I don’t see anything wrong with it.
(It’s kind of grown on me, actually
…though I do think kids in most parts of the U.S. would find it burdensome.)
My problem with it is that the name sounds too feminine, even in multicultural Melbourne. You’ll be virtually guaranteeing yer’ kid turns out ho-mo-sexual.
I 'spose you could always shorten it to Arnie but. No fears there of ambiguity. 
You have to remember that the boys’ name list gets “weird” a long time before the one for girls does, because each of the names at the top of the boy list is much more popular than the top girl names. In other words, male names tend to be much more conservative and less diverse.
It does rhyme with “piano” as I listen to that clip. Maybe my ear is not as nuanced as yours. But neither will be the ears of the 14 to 29 other kindergarteners sharing a class with your child, inevitably known as Tiano, Tiano, size of a Piano.
