LP Concert Series Bar Chimes have freer movement characteristics than the LP Studio Series. They feature gold-anodized aluminum alloy chimes and their stringing method with plastic ties allows for side-to-side movement yielding greater sustain and higher volume - perfect for live situations. LP Concert Series Bar Chimes are available in 25 and 36 chime single row bars. A bar chime striker is included. LP Bar Chimes now come in a protective tube that can be used again and again for transporting your chimes safely.
