Sound Inventions is a collection of 34 articles taken from Experimental Musical Instruments, the seminal journal published from 1984 through 1999 by Bart Hopkin. Bart enlisted Sudhu Tewari as co-editor of this book just published by Rutledge. I am very grateful that my article documenting the design of my Long String Instrument (from Volume 1, #2, August 1985) has been included.
