Recorders are made in different sizes. The lowest note of most recorders is either C or F. This is the note that is heard when the player covers all the finger holes and the thumb hole. The soprano recorder is the size of recorder which is usually played in schools, also known as a Descant. The lowest note of the soprano recorder is C. Some recorders are smaller than the soprano recorder but are not common. The alto recorder is bigger than the soprano recorder. Its lowest is F. The other main sizes are the tenor recorder (with lowest note C) and the bass (with lowest note F). Instruments larger than the bass are made but are not common. These include the Great Bass, Contrabass, Subgreatbass and Subcontrabass. Recorders higher than a soprano recorder include the Sopranino and Garklein recorders.
