l.h. jazz chords for r.h. melody with octaves with blocked chords for melody

[janyaporn]

Hello. I need a little help. I can play standards and pop from most sheet music, however, I recently learned a new r.h method for playing the melody and I am suppose to play jazz chords in the l.h.

Take a simple song in "C". Chords are C, F, G7, and some times Am. I need to play these chords as jazz chords - what? how?  All I know so far about jazz chords is to play a major chord as a 7th and a 7th as a 9th, and the minor as a minor 7th.

A friend taught me how to play the r.h. but only said to play jazz chords in the left hand. He is no longer available and I am lost.  I play the r.h. as follows.

For a r.h. C note I play a blocked chord and an octave together - C - E - G - C.   The single note melody of a song is always played with the r.h. pinkey. So the notes played on the r.h. with melody on the pinkey come out  C - dm - em - F - G -  am - B dim. regardless of l.h. chord.

Can anyone help me?  I hope you can understand what I wrote - I'm not very good at explaining things.

Thanks

As an add on to the above.  I forgot to mention yesterday that these blocked chords are fixed blocked chords.

Looking on the internet I found what I think he learned this from. U Tubes of a guy - Johnny102Melvin.  I watched the video and nothing was shown about the l.h. chords except to say that they were jazz chords.

Your question is extraordinarily broad which makes it a little hard to answer without writing a book on jazz voicings.

I'll refer you to one of my previous posts on the topic and you can see how you go.

^this explains rootless jazz left hand chord voicings at a level slightly above where I'd typically start people out. See how you go, you may have to alter them a bit to end up with something that works for what you're doing.

When doing block chords, sometimes its also good to also play block chords in the LH with them - works well if you split all the harmony up between the hands though - so both hands move in parallel with each other and together make up the whole block chord.
