I go up to around Eb5/E5 in falsetto but I only started using the basic falsetto slide a few days ago so I'm working on adding more notes :)

Oh right! Today i can't hit C6 in falsetto or full voice! But guys thanks again!

Man, that's a huge falsetto. At least to me; mine only goes to a G above tenor C and even then it is a strain. I don't mean to be a downer, but falsetto is very limited compared to full voice. Full voice can amass a very grand range where falsetto is limited to only about 2 octaves or so. If you cap out at Soprano C, that's normally it for falsetto. With full voice the sky is the limit.

Remember full voice consists of: chest, mix, head and whistle. Use falsetto as a tool in your arsenal but don't rely on it. That is what RYV is made for full voice POWAH! If you can hit C6 in falsetto, you will be able to hit it in full voice.

Whistle Will never be fullvoice in My opinion ;) and most metalsingers Lean on the falsetto function above E5 falsetto add twang and compression. But this is all down to what you count as fullvoice.

I can see why you wouldn't consider it full voice. It's thinner and very weak. I want to add my two cents as to why you should. If we compare chest, head, "super" head (head2). There is a noticeable change in tone quality when going from chest to head, a gap even. Same with head to head2. The voice gets thinner with less tone as the folds zip up. Keep in mind that whistle is only (to my knowledge) produced by the true folds. Whistle is thinner than chest more so then head and head2.

It is just the natural progression of the voice. I have heard some wickedly developed whistle. My ex had a loud, full and powerful whistle that would melt your face.

in my opinion there should be know line drawn between full voice and whistle.

Your thoughts, Jens?

Well now we are into terminology. When i hear the term fullvoice i Think about à tone with similar quality as speech. Whistle high and the higher part of" fullvoice" e5 and upwards almost never get such qualities.

Ive heard both Guys and girls do facemelter whistles and ive got à pretty decent one myself although it's not superloud. My strenght is more in head and head2 if you would describe it.
but My point is really, the Voice is made up by diffrent coordinations whistle is not head or head 2, whistle is whistle. Why group it all together and call it fullvoice?

To differentiate it from falsetto, I assume? It's only terminology...It's all one voice, really.

Yes its all one Voice. But whistle is not fullvoice its à diffrent coordination... You need to make à change around sopranos c.

you have one body but theres à reason you do pushups with your arms instead of your legs.

To entré whistle you need à high ammount of flageolett tension on your folds, That tension or coordination wont be there on lower notes. In whistlevoice there is no thickening of the folds as in fullvoice, no ta muscle active.

But sure its all terminology but i think its important That you know the diffrence for instance in My country fullvoice is basicly the Word for chestvoice. Good luck chesting That f7

I've been doing squats with my arms this whole time and now you tell me they are push ups?!?!

I think about what you've said.

Hehe yeah well when i wanted to explore whistle at first i just worked" zipping"and lighten but it didnt work. Not until i learned the right ammount of flageolett tension i was able to explore the E6 and above. Flageolett tension starts for makes just above C5 and is needed if you want to take the Voice higher.
Around soprano C the flageolett tension Needs to become very extreme, thats alo why some of the metalsingers high screams almost sounds like whistlenotes.

If that's true, that makes a lot of sense as to why I start to feel tension around D5...Maybe I need to start practicing whistle again..

Yeah your probably not used to the flageolet or has found the right coordination. But whistle is not the thing you should practice to get above the C5 area remember whistle is flageolet at the extreme. À hooty falsetto has alot easyer to activate thE flageolet then fullvoice. thats why jaime wants us to train the falsettoslide to get the Voice used to the flageolet so you can apply the sensation to fuller sounds.
Sofus of this forum had à really good exercisen for flageolet tension ask him if he can post it NeXT time he,s on. I cant share any clips fr.o.m. My iPad Else i had posted
