Welcome to the PianoGroove community!
With your experience of classical, jazz, and latin studies, I’m sure you will be able to dive straight into any of the material on the site.
We have put together a series of practice plans which help students to learn the foundational jazz theory in all 12 keys. I think it would be worthwhile to check out these posts:
You will likely be familiar with most of the material, but it may also highlight some gaps which you overlooked.
The more tunes we play, the more harmony we are exposed to, and so my recommendation is simply to study the tunes that interest you.
Also check out this video where I highlight the importance of regular listening and transcribing. That thread also contains links to listening/transcription exercises which are published weekly for our students to participate in.
The goal of these exercises is to improve our listening skills, empowering us to become self-sufficient learners so that we can listen to our favourite recordings, albums , and musicians to pick out material directly from recordings.
That way, we are taking ‘our sound’ in the direction that we want to take it - based on the sounds that we like - which is a very liberating point to get to as a musician.
I think you will enjoy Jovino’s Brazilian section of the website .
There is a beginner-focused Bossa Nova course taught by myself in there, but Jovino’s insights and experience are unparalleled in this field of improvised music, and so in terms of rhythm and groove, I think that his courses will give you the information you are looking for.
Finally, it is worth noting that many of the concepts covered in Jovino’s Bossa Nova courses incorporate theory covered in the jazz courses such as:
Our Rootless Voicings Course:
Our Altered Harmony Course:
Our Chord Substitution Course:
And so I would also recommend looking through those courses to familiarise yourself with the theory and the terminology.
There is a new Brazilian course to be published shortly on “Triad Approach To Improvisation” which was taught to Jovino by his mentor Hermeto Pascoal. I will be announcing this in the forum area shortly so keep your eyes out for that.
I hope this helps to give you some direction, and if you have any specific questions please don’t hesitate to let us know.
