This is your A Note In the 4th Octave Legacy Collection singing bowl. A masterpiece Legacy Collection Singing Bowl – an authentically hand-hammered bell-metal bronze singing bowl individually selected from hundreds of bowls to be an A note in the 4th octave. This bowl was selected for its musical note and octave, and with a unique Burnished Patina Relief process, was adorned with the Makers Mark “Ohm.” It will be approximately 5.25 inches in diameter, though we select for note rather than exact size -- so your forever bowl's size may vary slightly. The Legacy Collection was created to be modular, where you can easily build on to your collection over time according to musical duos, triads and scales. Every bowl in this collection is designed to blend seamlessly with the others. Rich, clear tone • Effortless rim-singing • Extra-long sustain. Each Legacy Collection bowl includes: Hand-signed 4×6 authenticity postcard (personally signed by the curator), specialty cushion and striker. These bowls are in the United States, made in limited quantities, selected from hundreds – and ready to be sent to you today.
