Hi m1469,
I use something called keepvid which allows me to slow down YouTube videos to 1/4 speed without losing sound entirely and as slow as .03 of recorded performance tempo with no sound. This "tool" also allows me to zoom in. This is extremely useful to me. Wait theres more, it also enables a slight change in the aspect ratio so you can view hands from a slightly different angle. A side view is not always best for me as I sometimes need to see the top of the hands to see which finger is actually being used. I may see the right hand clearly by one performer and have to use a different performer who recorded his performance from the other side to see the left hand clearly or just have another fingering "option" to try.
I have used YouTube many times for a variety of reasons:
1. Looking for new pieces I may wish to learn.
2. Fingering suggestions.
3. Different interpretations.
4. I have even watched the tops of peoples knees for pedaling. This is not easy to do.
I use a number of piano websites which are "subscriptions" under my YouTube account "1piano4joe" which I believe anyone interested could check out. I don't have any videos there but you were specifically looking for internet resources so I thought I'd mention it.
I use imslp and often will print out all the editions of a piece that I have decided to learn. For instance, I recently decided to learn Chopin Op. 69 No. 2 waltz in B minor. I purchased the Alfred edition of all Chopin waltzes edited by Willard A. Palmer from Sam Ash. In addition I printed from imslp versions/editions by Rafael Joseffy, Mutopia project, Kullak and another called D. & F. so five in all. There were more but I am selective. Pedaling, phrasing, dynamics and fingering are at times identical and at others quite different. This gives me "options" as I like to call them. I look at them and/or try them on for size just like a pair of shoes for the right fit.
Often I use plain old "Google. I find SheetMusicPlus a very useful tool as well. I guess I should mention pianoworld which is another great website.
While I can, and do, much of this on my own. It cuts down considerably on the "preparation work" that I do. More importantly, there are things that just don't occur to me to do and/or try. The results are:
1. Something that seems impossible becomes possible.
2. Something quite difficult could be manageable.
3. Something manageable becomes easy.
4. I've learned something for the next time.
Lastly, I had over 10 years of year round clarinet lessons as a child and was (at first) a music major in college. I gave up my teacher (sadly) and used the one assigned by the college. I felt I wasn't learning much there that I didn't already know. I had been giving woodwind lessons since the age of 14 and had students 30 to 40 years older than me.
Ultimately, I decided a career as a struggling musician was not a wise life plan. So, what kind of pianist/student, am I you ask. I don't know. I believe we are all Pianist/Teacher/Student all in one.
I choose to not give piano lessons but offer physics, chemistry, biology and calculus lessons. I am a New York state certified teacher with a M.S. in Education. I am no stranger to teaching people of all ages (Been teaching on and off since 1974 around 40 years?). My strong interest in science and mathematics were tarnished by teaching. I will not allow this to happen to music. That is mine. My only piano student is myself.
The piano is no longer one of my many "second instruments". Drums have made polyrhythms less difficult. Rhythm guitar, chords and rhythms. Lead guitar for solos. Bass guitar, well for bass lines. The organ unites these and was a trip as I had to read three staffs simultaneously but it was excellent preparation for the piano. I have studied these for years. The piano utilizes elements of each of these and so many more and has become not only my "first" but very favorite instrument!
So with this background, I consider myself a well grounded amateur intermediate classical pianist.
Till next time, Joe.
