$20 admission was justified by the quality and variety of exhibits in the museum. Fantastic location and building, very eye-appealing and beatifully landscaped. Great parking area with plenty of room though not shaded - but free. Beautifully designed exhibits and amazing number of display pieces. 2 levels with stairs, escalator, elevator access. Display areas are arranged geographically by continent and individual nation to show the instruments and relevant cultural heritage of music for each. Plenty of space to wander among displays without feeling crowded by other visitors. Make sure your batteries are charged if you want photos, you'll be taking a lot! Cameras/phones are allowed but no flash. Our photos came out great without the flash as lighting is very good without dark corners or shadows anywhere. Also several well placed benches to sit. Staff estimate it takes 3.5 hours to tour the museum if viewing all exhibits. We spent about 2 hours but easily could have spent longer reading and lingering. Unique and very well done, highly recommend.
