Hi all,
Having just recently retired (a young pensioner 
), I finally decided to learn the piano after many years of humming and hahing and generally finding work as an excuse to delay it.
I like music of all sorts, but feel that the piano just calls out to have relaxing jazz standards played on it.
I love the sounds of the ‘big voicing’ chords, and look forward to achieving the same with my own 2 hands.
Hi @markgrant 
Welcome to the PianoGroove community!
As a new piano player I’d recommend to start with our “Lead Sheet Fundamentals” learning path:
This learning path covers 9 beginner jazz standards which will help to build out your repertoire of songs.
We cover these 9 tunes throughout the PianoGroove courses and so learning the basic arrangement provides strong foundations upon which we can add more advanced theory and jazz harmonisation techniques.
I also recommend the theory lessons in our Jazz Piano Foundations course:
This theory takes time to learn (scales, triads, 7th chords, 251 progressions) and so spend 50% of your practice time on the theory lessons, and 50% on the jazz standard studies highlighted above.
You mention that you love the sound of big chord voicings, so here are some late-beginner/early-intermediate jazz piano lessons which I think will be of interest to you:
In these lessons I explain when and where these voicings can be applied - and so try to apply them to the beginner jazz standard lessons that I outlined in the “Lead Sheet Fundamentals” learning path.
If you have any questions, you can post in the “Comments” section of the lesson pages and that pings me a notification.
Click the link below for example and it will show you the Comment section which you will find on every lesson page on the website:
If you have a question specific to a lesson - that’s the best place to post it. You will also see the questions from other students and my answers which often contain useful information.
I hope that helps Mark.
Enjoy the lessons and talk soon!
