Shaw once wrote to Churchill:
/ˋˏʃɔː ˈwʌns ˈrəʊt | tə ˋˏtʃɜːtʃɪl. / 
“Here are two tickets for the first night of my new
/ˏhɪər | ə ˈtuː ˏtɪkɪts | fə ðə ˈfɜːst ˏnaɪt | əv ˌmaɪ ˌnju
ˋpleɪ. / 
One for yourself and one for a friend – if you have
/ˈwʌn | fə jəˏself | ən ˈwʌn | fər ə ˋfrend | ˋʔɪf ju ˋˏhæv
wʌn. / 
/ ˋtʃɜːtʃɪl rɪˋˏplaɪd: / 
“Dear Bernard, I’m sorry, but a previous
prevents me from accepting your kind offer.
/dɪə ˋbɜːnəd | aɪm ˋˏsɒrɪ | bət ə ˈpriːviəs ɪŋˏɡeɪdʒmənt | prɪˋ-vents mi | frəm əˋ-kseptɪŋ | jɔː kaɪnd ˎɒfə./ 
However, I shall come to the second night — if there
/haʊˊˋevə | aɪ ʃəl ˈkʌm | tə ðə ˋsekənd naɪt — ɪf
ðeər ˏɪz wʌn./ 
The first consonant of "first night" is no doubt contaminated
preceding dental fricative beginning the previous word so that what we
hear for "first" might equally well have been have been "thirst".
Perhaps I shd remind readers ("if there are eni!") that,
transcribers, I make full use of the normal punctuation only
supplementing it when it isn't adequate etc. Thus in our first line I
avoid the needless clutter of a vertical bar after the first word
because it's obvious that the second word begins a new unit. If this
second word had been unmarked for pitch I shdve been obliged to insert
the bar to avoid the suggestion that it was incorporated in the tail of
the foregoing Fall-Rise.
Another point this line illustrates is that not all High tones
equally high: the Fall-Rise on the last word is distinctly less high
than the one on the first. The words "my new" are spoken on two low
level tones of which the second is slightly higher than the first so we
can term it as a Bass head: successive High tones step down and
successive Low tones step upwards. Another item we meet for the first
time in this passage is the Slump-Rise climax tone. It's often
difficult to decide whether to regard such a descending-ascending
sequence as Slump-Rise or Fall-Rise as in this case. Most writers don't
offer themselves choice.
The Alt-plus-Rise pattern repeated here on "two tickets" and
night" has quite a patronising effect: Alts are regularly associated
with the unemotional calmness of a person in complete and confident
control of things; Rises are regularly associated with attitudes like
encouragement — even as here to a person who wdnt welcome
any. The glottal plosive we've shown at the beginning of "if you have
one" is of course not part of our segmental transcription, which is
strictly phonemic, but a prosodic item. We shan't indicate all such
possibilities but this seems a more vigorous one than most —
many being quite weak.
The word "However" shows from our reader (a distinguished
actor himself ) a restrained but very effective little piece of character acting.
Churchill was very famous for his old-fashioned very oratorical style
of speech-making in which he very often employed deliberately delivered
ascending-descending tones one of which is the Climb-Fall we have here.
By his choice of simple Rise (not Fall-Rise as we might expect and
heard from Shaw) he is also being patronising back to Shaw by sounding
encouraging. A very great deal of the difference between a mediocre and
an excellent spoken performance must surely reside very much in the
prosodic choices made by the speaker.
