I previously wrote how it is sometimes difficult for new mambo dancers to hear and dance to the beat of the music. There is an app I use in my teaching to help my students dance on the beat and in time with the music. It's called the Salsa Beat Machine/ Salsa Rhythm Machine which can be downloaded from Google Play or the App Store. The app can isolate and play each salsa instrument and play each one at a different bpm ( beats pper minute ) . It even has an instructor voice that can call out the timing of the music and set the clave 3/2 or 2/3 . It doesn't matter if you dance ON1 or ON2 .Get this app. It can really help your mambo dancing .Keep on dancing !
