Can Not Access The Head Voice

New to the program and I am here to solve an issue I have been having with not having access to my head voice.  Its as if I'm completely limited to chest voice and any attempt reaching higher notes equates to a strained throat sound. 

For Context, I can not make the "Woo" sound you may here from someone receiving happy news.  Trying to make an owl's "Who" sound only comes out as a flat talking tone.  Finally, Speaking in a Mickey Mouse tone has just been impossible. 

I am certain it is a technique issue and I'm willing to put in the work to break down this barrier but I do not see any instruction as to how to specifically access the head voice.

If anyone has had similar issues and have overcome this struggle please let me know your methods and practice exercises.  This is my primary goal for my membership here and I hope to find a suitable means to do so.  Thank You

Hi, Ricciardi! What is the highest pitch you're able to produce sound on? I usually encourage low voices to start around G4 or A4 when attempting head voice. 

It's usually helpful to sing very quietly (even breathily), use vowels like OO or EE (or any of the sounds you mentioned), and try something semi-closed for more support (like a lip trill or straw singing). 

If you haven't tried straw singing, take a drinking straw and submerge it into a glass of water (filled halfway). Sing an "oo" through the straw so that sound and bubbles are happening simultaneously. Singing through a straw can help students find their head voice function, because it lowers the point at which you naturally transition to head voice, requires breath flow, and narrows the vocal tract.

Thank you.  I will try those and see if there is any progress.  As for my highest note, I will have to get back to you.  I'm fearful that it is dreadfully low. 

Something I should mention, in your hour long discussion on the second link provided, at the 6:30 Mark you ask the viewers to do a "woo" sound.  I literally can not, no matter how hard I try, create that sound.  That is the basis of my dilemma.  All of the exercises are great, but I can not access the head voice at all.  I know there are others like me, have you had any students with similar issues and know what they did to overcome it?  Often, it seems, that people without a certain challenge like this may not beable to help crack the code.  This is my main focus this month.  If you can provide some insight on that I would really appreciate it.

I understand! Yes, I've had a few students who were unable to make any noise in head voice. I typically recommend getting scoped by a laryngologist to make sure there's no physical issue first, since lack of head voice is one sign of issues with the vocal folds. However, if you've never used that function in your life, that can also explain your difficulty. 

A classical teacher may make an argument that if you're a very low, heavy voice (a true bass), you may not need to explore head voice and can choose songs that fit within your comfortable chest voice range. I always encourage head voice, because it's needed in most contemporary singing. 

What I've found to work best is straw singing, described in my last comment! If you'd like to book a lesson, I recommend working with Abram, since he's a male singer and can demonstrate in your range: https://www.30daysinger.com/live-lesson
