Love this thread guys, because I simply love latin and latin jazz rhythms since I started to played it.
In my honest opinion every bass player should start learning and playing a bit of latin, the boost this style gives to your time keeping skills is second to none, that's why it's one of the topics I always add to my bass lessons.
The first and probably best suggestion for me to help solve your problems is to learn and develop your counting and rhythm reading, it's the only key man, Latin has no shortcut and it's the only style of music where all the instruments fit into each other like a jigsaw puzzle and if you're just a bit behind or ahead the click; everyht falls through like a domino.
But counting and consequently rhythm reading, it's not only important for you to improve the way you play the groove correctly, tumbao is only one of them (montuno, guaguanco, samba, mambo, cha, songo and many more), but MOST IMPORTANT to help you to play the specific groove and be INDEPENDENT of what others are playing, especially piano and other rhythm instruments, because in 90% of the scenarios you are playing groove lines that wedge into the others open spots.
Now it's easier than it seems, so my suggestions are
- Learn to count with your voice while playing, always with the standard click,
- start with a slower tempo, learn your latin grooves from 60 bpm, then jump by 20bpm, for example 60-80-100-120 etc, this will help you to improve your time keeping jumps, especially as most latins are cut times, and you will be faced with very fast rhythm grooves,
- Then, after you have played a groove correctly, switch the metronome to a clave click, 3:2 or 2:3, no matter, you have to feel completely natural when you play it,
- last but not least, test your playing with the mp3 etc., if you have done the previous steps correctly, you have definitely improved your skills.
Here's an example of playing a Latin jazz groove with a clave click.
I hope my suggestions help you and if you need more, just let me know.
