pianola 15
Mechanical piano, which has built-in an ingenuity for playing parts that were originally written on perforated tapes. In lunfardo is another version of the "pianito", a record sheet where the inked fingers were supported to record the fingerprints of the criminals. The methonymia mentioned in other definitions as 'denture' is because of its similarity to the ivory keyboard, and if it has missing pieces, it would be ebony keys.
