class instrumenttools.Accordion(instrument_name='accordion', short_instrument_name='acc.', instrument_name_markup=None, short_instrument_name_markup=None, allowable_clefs=('treble', 'bass'), pitch_range='[E1, C8]', sounding_pitch_of_written_middle_c=None)

Accordion.

>>> import abjad
>>> staff_group = abjad.StaffGroup()
>>> staff_group.context_name = 'PianoStaff'
>>> staff_group.append(abjad.Staff("c'4 d'4 e'4 f'4"))
>>> staff_group.append(abjad.Staff("c'2 b2"))
>>> accordion = abjad.instrumenttools.Accordion()
>>> abjad.attach(accordion, staff_group[0][0])
>>> abjad.attach(abjad.Clef('bass'), staff_group[1][0])
>>> show(staff_group) 

The accordion targets the piano staff context by default.
