To encode notes in Pizzicato
without using the mouse or computer keyboard, the only solution
is MIDI. Usually, one thinks that we are limited to a synthesizer
keyboard, organ or MIDI compatible electric piano and people not
playing the keyboard find themselves disappointed.
You must know that various MIDI
converter exist for acoustic instruments like guitar, sax, bass,
violin, brasses, battery,... and even the human voice. Such a
converter is often specific for an instrument, but it provides a
MIDI output that can be used directly by Pizzicato to encode the
notes of a score rapidly.
This type of converter may be
found in specialised music stores. A MIDI cable connects it to
the computer and from there, any MIDI musical software may use
the notes played on your guitar, violin, sax,...
