There are quick paced, adventurous, energetic tracks and gentle easy going commercial background music that are pleasant, relaxed, and have a warm romantic nostalgic feel. These clips have acoustic ukulele (an antique acoustic 1930's Richter), melodic acoustic guitar, driving 5-string bass, real maraca, and hand clapping. You can't find any more energy or impart an uplifting walk on a tropical beach feel better than with a ukulele. It's great for energized excitement such as beach recreational sports, corporate, business, background, travel, fast motion, or any adventurous activity like ocean surfing and water skiing. There are nice melodic strumming and an agreeable sweet tone that imparts you into a good feeling happy mood. Sit in the palm tree shade sipping a cold margarita tapping your feet and pass me another drink please the hula dance is about to start!
