There are  piano instruction software packages available other than 
Voyetra's "Teach me Piano" which you may also wish to explore.  One 
example is Piano Suite or Piano Suite Premiere from the Canadian 
company, Adventus Software 
(http://www.adventus.com/products/Premier.html).  This is also a good 
package, although I find a good deal of the material in Piano Suite is 
aimed primarily at teaching children to play, with games, etc.  Another 
package that is quite good is by Yamaha and is called "Enjoy!! Portable 
Keyboard", although I am not able to find this on the U.S. Yamaha web 
site.  I did purchase this package from the U.K. via the web.  

Of all of the piano instruction packages that I have considered, I like 
the Voyetra "Teach Me Piano" package best because: ( It is clearly aimed 
at the adult and at serious students of the piano.  One reviewer of this 
software described it as the "Julliard School for Home instruction". 
 While I think that is a bit of exaggeration, "Teach Me Piano" with its 
150 lessons and some 75 musical selections does offer a solid and well 
designed piano instruction package.  The accompaniments played through 
the tone generator are fun and also tastefully done.  I loved the music 
in this package!  I have spoken personally about a year ago with Mr. 
Hugh Berberich who designed the "Teach me Piano"  musical course, and he 
and I both have tried hard to get Voyetra to expand this package and 
also to correct some bugs that are in the program.  Unfortunately, 
Voyetra seems to have little interest in correcting the software bugs. 
 Nonetheless, this is still a very worthwhile introduction to the piano 
for serious students.  

With all of the above said, no software, regardless of how well 
designed, can be a substitute for a good piano teacher, as I have 
discovered over the last year after completing the "Teach me Piano" 
course and taking lessons from a good teacher.
