1. The basic tones, shown in the table, are taken according to the official data, pub-lished by the enterprises themselves.
2. As the bell-founders say, the basic tones, pointed in the advertisement, may vary (sometimes in wide limits according to our measures).
3. It’s necessary to keep in view that Russian bell-founders don’t have a unique method of determining bells' highness, that’s why you shouldn’t always believe the basic tones, written in the advertisements. Some producers take the strongest overtone for the moment of verberation as the basic tone, others – the second (fundamental) overtone (as in the West), others – the so-called “verberation” tone (the tone, which is felt at the first moment after the verberation, it’s rather subjective), others take the lowest tone (undertone; it can be easily determined and finishes the sounding of every normal bell) as the basic tone, taking to consideration that the strong-est tone in Russian bells isn’t stable. The Bell Centre (as well as the foreign specialists, which have consulted it) considers the undertone’s taking to be the most correct method to determine the basic tone in Russian bells.
