Pitches entry 2 - accidental signs

A sharp is formed by adding -is to the end of a pitch name and a flat is formed by adding -es. Double sharps and double flats are obtained by adding -isis or -eses. These names are the Dutch note names. In Dutch, aes is contracted to as, but both forms are accepted. Similarly, both es and ees are accepted.
