Thank you all

I'm learning Korean and I find watching music videos with the lyrics on youtube really helpful

Tree or Three I find at: http://www.freebookspot.es/Comments.aspx?Element_ID=52276 But be careful with these downloads, they often have a 'gotcha'

There are two books 'Tree or Three' and 'Ship or Shape' that give excellent diagrams for mouth tongue lip positions plus DVD or MP3 Both books are written by "Ann Baker"

thank u very much WashingtonWA
