Instruments should be filled in as 1pf, 2vn, 1C+, etc. For specific search (check the field “only“) a comma follows the instrument and the number of instruments precedes the instrument (applies also if you search one instrument only). If the instrument is not indicated in the given form, search results will include all the pieces, in which the given line is present (e.g. filling in t will produce search results also with tr, tn, bat, etc.).
Check in the “only“ box if you search pieces including only the instruments you had specified. If the box remains unchecked, search results will bring information on all pieces including the instruments you had specified (and others).
Do not use diacritics, parentheses, or quotation marks, and do not indicate numbers following the instrument.
With duration and year of origin indicate the time period From – To. If you prefer to use a criterion of one figure, fill in the figure in both fields. With minutes and seconds use the English keyboard keys ' (min), '' (s), eg. 3' 20''.
