Listen to Latin music. Find CDs, download songs, or go to clubs or bars where Latin music is played. Before you can play Latin sounds on the piano, it is important to introduce yourself in the basic form.
Check out different Latin music styles. Salsa piano can be written with a 12/8 time signature, when the most common is 4/4. Play a tango piano a bit faster, with more breaks than a traditional, non-Latin sound. Syncopate in bossa nova style piano.
Find sheet music for tango, bossa nova, salsa, merengue or mambo. Alternatively, you can play for ear, listen to different composers (eg Tom Jobim) and try to mimic or recreate the sound.
Start sharing away from sheets of music and composers, and compose or improvise your own piece. Knowing the basic rhythm, breaks and different types and styles gives you an idea of how to create a tango on piano, even if it is not a masterpiece.
Playing Latin sounds on the piano requires no special piano or skills, just a different type of playing style. Instead of learning new techniques, you need to listen and understand the basics of Latin music. A piano is a versatile instrument and can produce more than classical, jazz or blues. Playing different sounds on the piano only requires an interest in a certain style and practice.
