On the [[Xenharmonic Alliance]] Discord in September 2025, [[Maeve Gutierrez]] noted that the notes of [[3ed7/3]] make for a nice chord when played simultaneously. [[Budjarn Lambeth]] noted that 9ed7/3 is a good tuning for using said chord. | |||
Lambeth suggested the following mappings for using 9ed7/3 on an [[isomorphic keyboard]] like the [[Lumatone]]. He suggested using 1\9<7/3> for the x-steps and 3\9<7/3>\49 for the y-steps or vice versa. | |||
This gives easy access to Gutierrez's 3ed7/3 chord above any note, while also allowing satisfying bends using the [[neutral second]] interval of ~[[11/10]]. | |||
